Description:    This paper reports on a study of the Seebeck coefficient and power factor κ of p -Bi 2 − x Sb x Te 3 solid solutions with different contents of antimony atoms in the bismuth sublattice for x = 0, 1.4, 1.5, and 1.6 under variation of pressure of up to 15 GPa. The magnitude of κ has been found to grow nonmonotonically within the pressure region of 2–4 GPa. The effective mass of the density of states m / m 0 and the mobility μ 0 have been calculated with due account of degeneracy within the parabolic model of the energy spectrum assuming isotropic charge carrier scattering. It has been shown that application of pressure brings about a decrease of the effective mass m / m 0 and an increase of carrier mobility. The power factor κ of the p -Bi 0.6 Sb 1.4 Te 3 composition exhibits at the pressure P ≈ 4 GPa the largest increase of the power factor κ as a result of a weak decrease of the effective mass m / m 0 and an increase of carrier mobility as compared to the other solid solution compositions. The specific feature of the variation of the power factor κ with a change of the pressure in bismuth telluride near P ≈ 3 GPa, which is accompanied by formation of a knee in the m / m 0 vs. P dependence, can be assigned to an electronic topological transition.

Description:    Neutron diffraction studies of many magnetoelectrics and corresponding symmetry analysis indicate that the description of their magnetic structures requires of invoking two or more order parameters, so that the temperature proximity of their “condensation” has to be postulated when constructing a consistent thermodynamic theory. In this work, MnWO 4 , CuO, and CuCl 2 magnetoelectrics are analyzed from the standpoint of symmetry of the exchange Hamiltonian. The magnetically ordering states observed in them are shown to be induced by one irreducible representation of the symmetry group of the exchange Hamiltonian. This fact provides the proximity of corresponding instabilities in the thermodynamic path and some features of magnetoelectrics.

Description:    Dispersion properties of circularly polarized eigenwaves propagating in the “semiconductor-magnet” layered periodic structure along the axis of its periodicity and external magnetic field have been considered. The possibility of controlling the effective material parameters of the structure and the feasibility of negative refractive index for the wave with right (resonant) circular polarization has been shown. High magneto-optical activity of this gyrotropic structure has been ascertained, which leads to large Faraday rotation angles if the structure is in the state of “left-handed” medium.

Description:    The interaction of ytterbium nanofilms evaporated on tungsten substrates with oxygen has been studied by Auger electron spectroscopy, thermal desorption spectroscopy, and contact potential difference measurements. It has been shown that at room temperature, no oxide is formed in the above interaction. In place of the oxide, a chemisorbed layer of nondissociated O 2 molecules is formed on the surface of the ytterbium nanofilms. This layer modifies the ytterbium. This modification transforms ytterbium from the divalent state into the trivalent state.

Description:    The behavior of the impedance spectra of island permalloy films prepared through vacuum evaporation onto optically polished glass-ceramic substrates has been investigated in the frequency range from 0.0001 to 100 MHz. A resistor-capacitor model of the films has been developed and the model parameters, for which there is a good agreement with experimental data on the frequency dependences of the real and imaginary components of the impedance, have been determined. The specific features in the behavior of the electrical and physical characteristics with variations in the thickness of the sample and the gap between the measuring electrodes have been investigated. It has been found that the relative permittivity of the films under investigation reaches values ɛ ∼ 10 7 –10 8 . The structural relaxation times have been calculated.

Description:    The influence of the first-order phase transition on the parameters of the potential barrier at the indium/polymer interface has been investigated. It has been established that the phase transition occurring in the metal initiates switching of the polymer insulator into a high-conductivity state. Performed investigations have shown that the main charge transfer mechanism in the metal-polymer-metal structure at high temperatures is the current caused by the electron thermionic emission. The analysis of current-voltage characteristics has demonstrated that the first-order phase transition in indium leads to the variation in the potential barrier height at the metal/polymer interface by Δφ ≈ 0.18 eV. It is this phenomenon that is responsible for the electronic switching. Content Type Journal Article Category Metals Pages 243-247 DOI 10.1134/S1063783412020199 Authors I. R.

Description:    A model of electron transfer by tunneling between trapped electron and hole centers in crystals with hydrogen bonds under the conditions of thermostimulated mobility of one carrier type in the recombination process has been developed. The proposed model describes all features in the kinetics of induced optical density relaxation observed in nonlinear optical crystals of KH 2 PO 4 (KDP) and NH 4 H 2 PO 4 (ADP) on a wide temporal scale (10 −8 –10 s) under pulsed irradiation. The results of model calculations have been compared with experimental data on the photoinduced transient optical absorption (TOA) in KDP and ADP crystals in the visible and UV ranges. The nature of the radiation-induced defects, which account for the TOA, and the dependence of the TOA decay kinetics on the temperature, excitation power, and other experimental conditions have been considered.

Description:    The differential magnetization of LaCoO 3 in magnetic fields of up to 500 T has been measured at a temperature of 4.2 K. The magnetization curve reveals several features which suggest a complex pattern of the transition of LaCoO 3 from the low-spin state to the high-spin state. The magnetic moment starts to grow in fields above 50 T to reach a plateau in the 130–240-T region, after which the magnetic moment continues to rise up to saturation in fields ∼500 T.

Description:    The magnetic-field-induced optical alignment-orientation transition in a system of triplet bound excitons in a resonantly excited GaSe crystal has been studied using optical spectroscopy. It has been demonstrated that this effect can be assigned to a variation of the properties of Zeeman (spin) states of triplet excitons in a magnetic field, which initiates a change in the optical activity of these states in circularly and linearly polarized light. For the transition to become possible, the model requires that the electronic system of the crystal supports spin-orbit coupling. The approach employed permits the adequate description of experimental data, as well as calculation of the evolution of the effect during the bound-exciton lifetime.

Description:    This paper reports on the results of the investigation into the dielectric properties of perovskite ceramics of the relaxor ferroelectrics (1 − x )(NaBi) 1/2 TiO 3− x Bi(ZnTi) 1/2 O 3 ( x 〈 0.2) with the use of the impedance spectra measured in the frequency range from 25 to 106 Hz at temperatures from 100 to 1000 K. It has been found that the temperature dependence of the real part of the permittivity is characterized by a maximum at a temperature T ′ m (590–610 K). It has been shown that, in the temperature region of the existence of the relaxor state ( T 〈 T ′ m ), the permittivity ɛ is determined by the sum of the contributions from the matrix and dipole clusters. The temperature dependence of the contribution from the clusters, which is determined by the kinetics of their formation and freezing, is characterized by a curve with a maximum. It has been revealed that, in the temperature range T 〉 T ′ m , there are two mechanisms of polarization. One mechanism is associated with the thermal hopping motion of charges, whereas the other mechanism provides an induction-type response (system with a negative capacitance). The latter makes a negative contribution to the real part of the permittivity ɛ and a positive contribution to the imaginary part of the permittivity. A quantitative analysis of the experimental data has been carried out with the use of an equivalent circuit that includes a constant-phase element of the induction type.

Description:    A model has been developed for nucleation and growth of particles of the second phase in alloys based on the Fe-Cr system. It has been assumed that the main mechanisms of change in the distribution of phases in the alloy are the fluctuation activationless nucleation of clusters enriched with chromium and their subsequent growth due to the diffusion of chromium atoms. The model is applied to the description of the growth kinetics of particles of the second phase in the alloy Fe- x Cr ( x = 14, 16, 18, 20 at %) at the temperature T = 500°C. The obtained values of the diffusion coefficient D Cr = 3.12 × 10 −19 cm 2 /s and the rate of fluctuation nucleation (decomposition) of the clusters τ −1 = 0.868 × 10 −3 s −1 are consistent with the data available in the literature.

Description:    Based on the developed technique for synthesizing spherical mesoporous particles of yttrium oxide with a size dispersion of 10–15% and methods for infiltrating active components into them, spherical nanocrystalline particles of composition Y 2 O 3 -ZnO have been synthesized. The nanocomposite structure has been studied, and the spectra of diffuse reflection and photoluminescence of heteroparticles, as well as the stimulated emission spectra of zinc oxide excitons, have been analyzed after annealing at various temperatures. The formation of ZnO nanocrystals in Y 2 O 3 sphere pores is observed during material synthesis with a single infiltration procedure. The lasing is associated with a change in the effective refractive index and local photon density of states in phosphor nanoparticles, i.e., spherical optical cavities.

Description:    The spectral and temporal characteristics of X-ray luminescence of composites consisting of microparticles of “heavy” components (oxides, fluorides, sulfates) and an organic polymer binder containing optically active impurities have been investigated. It has been found that, in the case of pulsed X-ray excitation of the composites with a photon energy of 130–150 keV, the fast component (τ 〈 10 ns) of the luminescence arises whether or not the “heavy” component of the composite is doped with an optically active impurity. A mechanism has been proposed for the formation of the fast component of the luminescence: electrons and low-energy X-ray photons generated during the interaction of high-energy X-ray photons with the “heavy” component of the composite are effectively absorbed by the polymer binder and, thus, induce its luminescence. It has been shown that, in order to produce a composite-based fast scintillator with a high light yield, it is necessary to use a binder prepared from an organic material with a short scintillation decay time and another component prepared from a compound whose composition includes an element of a large atomic number Z .

The presence of the TGS and ATGS textures in pores of Al 2 O 3 films has been found. It has been established that, under conditions of confined geometry, the broadening of diffraction maxima of the reflection is caused by the size effect.

Description:    The phenomenon of surface plasmon resonance in composite films consisting of gold nanoclusters in matrices of organic molecular materials calix[4]arene and poly(N-vinylcarbazole) has been investigated. The internal reflection coefficients R s 2 and R p 2 of s - and p -polarized light and their physical difference ρ = R s 2 − R p 2 have been measured according to the Kretschmann scheme as a function of the angle of light incidence θ at different wavelengths λ in the range 400–1000 nm. The angular characteristics reflect the cluster structure of the films, which is confirmed by electron microscopy. A topological size effect has been revealed. This effect is associated with the dependence of the excitation energy efficiency of surface plasmons on the azimuth of the linearly polarized light, the shape, and the distribution of nanoclusters in the coordinate space. The dependences ρ(λ) demonstrate that the local plasmon resonance is excited by both s - and p -polarized light, whereas the polariton resonance is excited by s -polarized light. The sign of the curvature of the dependence ρ(θ) determines the predominance of the excitation energy efficiency of electromagnetic modes with one of the two states of polarization of the excitation radiation.

Description:    The domain structure in a biaxial ferroelectric layer perforated by cylindrical channels has been investigated using the numerical simulation based on the phenomenological theory of ferroelectricity and the equations of electrostatics in the framework of the Gauss-Seidel iterative method. Both polar axes lie in the plane of the film, which is characteristic of thin epitaxial films of BaTiO 3 and (Ba 1 − x Sr x )TiO 3 on a MgO substrate. The calculations have been performed using the parameters of BaTiO 3 , which does not matter because of the qualitative character of the results: the electrostatic problem is two-dimensional and formally applies to infinitely thick layers rather than to thin layers. The primary attention has been paid to the systems containing sixteen channels. Two different orientations of the polar axes with respect to the lattice channels have been considered. It has been shown that, for these orientations, the domain structure has a different character: when the line with the minimum distance between the channels is perpendicular to the bisector of the angle between the polar axes, this structure contains a single channel in the repeating motif and a polarization vortex; when one of the polar axes is perpendicular to the line with the minimum distance between the channels, the situation is less clear. There are indications that the repeating motif of the domain structure in a system of many channels contains two channels and does not contain vortices. The strong influence of the electrodes on the domain structure in this case has been noted.

Description:    The 55 Mn NMR studies of nano-sized and polycrystalline La 1 − x Ca x MnO 3 samples have been performed. It has been shown that a decrease in the average size of the nanoparticles leads to the disappearance of the phase separation of the ferromagnetic phase, which is likely a general property of manganites. The studies in constant magnetic fields have demonstrated that the phase separation under consideration occurs within domains rather than as a result of the separation of the samples into domains and domains walls.

Description:    The influence of an electric field on stable photostimulated triplet states of NH 4 BPh 4 at a temperature of 77 K have been studied by EPR spectroscopy. It has been established that, on exposure to UV radiation, electron capture by traps in the band gaps takes place with formation of triplet state. After application of an electric field, triplet states are destructed because, with an increase in the applied voltage, a gradual inclination of energy bands takes place and electrons found in traps on different energy levels are released. The assumption that captured electrons are found in traps on different energy levels is confirmed by earlier studies of thermoluminescence spectra.

Description:    Quantum oscillations of the resistivity ρ 22 and Hall coefficient R 12.3 in the semiconductor alloy n -Bi 0.93 Sb 0.07 have been studied at H ‖ C 3 and j ‖ C 1 in magnetic fields to 14 T and at temperatures of 1.5, 4.5, 10, and 20 K. At temperatures of 1.5 and 4.5 K, beats of quantum oscillations of ρ 22 and R 12.3 due to a small deviation of the magnetic field H from the crystallographic C 3 axis have been observed. To determine the oscillation period Δ i , cyclotron mass m ci , cyclotron frequency ω ci , and extreme section S extri , experimentally measured quantum oscillation beats have been compared with the model beats of oscillations of three harmonic functions, two of which have close frequencies. The deviation of the parameters Δ i , m ci , and S extri from the same parameters when the magnetic field H exactly coincides with the trigonal C 3 axis has made it possible to estimate the magnetic field H deflection angle from the trigonal C 3 axis, which is ∼1°.

Description:    The results of electron paramagnetic resonance (EPR) studies of Ce 3+ impurity ions in single crystals of lead thiogallate PbGa 2 S 4 have been reported. The Ce 3+ ions substitute for Pb 2+ ions in the crystal lattice of PbGa 2 S 4 . A number of paramagnetic cerium centers in lead thiogallate have been observed. The spectra are described by the spin Hamiltonian of rhombic symmetry with the effective spin S = 1/2. The g factors of the main cerium centers have been determined. A large number of paramagnetic centers are due to both nonequivalent positions of lead and local charge compensation under the substitution Ce 3+ → Pb 2+ .

Description:    The temperature dependences of the capacitance and conductance measured for samples of porous aluminum oxide films with inclusions of triglycine sulfate have been investigated. The character of these dependences obtained for the films treated in a humid atmosphere differs from that of the corresponding dependences measured for the initial porous Al 2 O 3 matrix, bulk triglycine sulfate, and dried Al 2 O 3 + triglycine sulfate composite. The observed changes are determined by the influence of the water adsorbed on the surface of the film and the water structured in pores of the composite.

Description:    The influence of a magnetic defect on the field distribution and magneto-optical properties of a one-dimensional photonic crystal has been investigated. It has been shown that the maximum localization of the wave field in the defect layer is achieved in an asymmetric photonic crystal structure. A greater Faraday rotation, which significantly exceeds the angle of rotation of the polarization plane in an isolated magnetized layer, and a higher degree of localization of the wave field can be achieved when the magnetic layer is surrounded by layers of photonic crystal mirrors with a lower refractive index. An increase in the Faraday rotation angle is determined not only by an increase in the thickness of the magnetic defect but also by a symmetric increase in the number of periods in the photonic crystal mirrors.

Description:    This paper reports on a thermal desorption spectroscopy study of the interaction of chemisorbed molecules of oxygen and carbon monoxide with ytterbium films of nanosized thickness formed on the surface of silicon substrates at room temperature. As follows from the results obtained, at 300 K, the CO and O 2 molecules reside on the film surface in chemisorbed state and do not dissociate under these conditions into atoms. The molecules decompose at high temperatures. The oxygen released in the process reacts with ytterbium and silicon to form silicate compounds, which decompose at still higher temperatures.

Description:    The deformation surface pattern generated on the faces of a copper single crystal loaded by a compression force and simultaneously sliding over the counterbody surface has been studied. The samples under study are copper single crystals with different orientations of the compression axis, which are grown by the Bridgman method. The study of the friction of single crystals with the orientations [110] and [ - 1   11] has revealed that the shear systems whose action manifests itself on side faces are localized near the friction zones. The density of traces formed in this process decreases with the distance from the butt-end. The [110] single crystal has regions of higher density near the butt-end. Different patterns of shear on the side faces of [ - 1   11] single crystals, resulting from the friction and uniaxial compressions, have been observed: they consist in the absence of deformation macrobands during friction.

Description:    This paper reports on the results of the 57 Fe Mössbauer investigation of the short-range order in FeCoZr nanoparticles and also the studies of the electrical and magnetotransport properties of (FeCoZr) x (CaF 2 ) 100 − x granular nanocomposite films in the concentration range x = 16–75 at %. A correlation between the oxygen partial pressure during the synthesis of nanocomposites and the magnetic state of iron-containing nanoparticles has been established. The influence of the oxidation of metallic particles on the electron transport mechanisms and on the magnetoresistance of the films has been analyzed. It has been found that, in the nanocomposites with a high FeCoZr concentration ( x ∼ 70–75 at %), there is a preferred orientation of the magnetic moments of α-FeCo(Zr) nanoparticles in the direction perpendicular to the film plane.

Description:    The genetic origin of a ferroelectric crystal of guanidinium aluminum sulfate hexahydrate has been established and the spectral dependences of the electron density of states, the electron energy, and the optical functions ɛ 1 ( ħ ω) and ɛ 2 ( ħ ω) for this crystal have been calculated in terms of the density functional theory. It has been found that there is a weak dependence of the energy of electrons in the upper valence bands on the wave vector. The calculated values of the band gap ( E g ∼ 5.44 eV) and refractive indices are in agreement with the experimental results. It has been shown that there is a strong anisotropy of the spectral band ɛ 2 ( ħ ω) in the region of 6 eV, which is predominantly formed by the p states of carbon (∼60%) and nitrogen (∼40%) atoms of the C(NH 2 ) 3 group.

Description:    Samples of β-SiC/Si ecoceramics with a silicon concentration of ∼21 vol % have been prepared using a series of consecutive procedures (carbonization of sapele wood biocarbon, synthesis of high-porosity biocarbon with channel-type pores, infiltration of molten silicon into empty channels of the biocarbon, formation of β-SiC, and retention of residual silicon in channels of β-SiC). The electrical resistivity ρ and thermal conductivity κ of the β-SiC/Si ecoceramic samples have been measured in the temperature range 5–300 K. The values of ρ Si chan ( T ) and κ Si chan ( T ) have been determined for silicon Si chan located in β-SiC channels of the synthesized β-SiC/Si ecoceramics. Based on the performed analysis of the obtained results, the concentration of charge carriers (holes) in Si chan has been estimated as p ∼ 10 19 cm −3 . The factors that can be responsible for such a high value of p have been discussed. The prospects for practical application of β-SiC/Si ecoceramics have been considered.

Description:    The electronic structure of diphenylsilane Ph 2 SiH 2 has been investigated using X-ray emission spectroscopy and quantum-chemical calculations in the approximation of the density functional theory. The SiK b 1 X-ray emission spectrum of Ph 2 SiH 2 has been constructed using the results of theoretical calculations. The energy structure and shape of this spectrum are in good agreement with the experiment. A comparative analysis of the results of calculations and the fine structure of the experimental SiK b 1 X-ray emission spectrum of diphenylsilane has made it possible to describe in detail the specific features of the chemical interaction in this compound. The quantitative characteristics of the hybridization of atomic orbitals in the studied molecule have been obtained by analyzing the natural bonding orbitals.

Description:    The subnanosecond time-resolved ultraviolet luminescence of Li 6 Gd(BO 3 ) 3 : Ce crystals under selective excitation by ultrasoft X-rays in the region of the 4 d →4 f core transitions at temperatures of 7 and 293 K has been investigated for the first time. The performed investigation has revealed the following features: an intense fast component of the luminescence decay kinetics in the subnanosecond range due to the high local density of electronic excitations and the processes of Auger relaxation of the core hole; the modulation of the luminescence excitation spectrum by the “giant resonance” absorption band of the 4 d -4 f photoionization in the energy range 135–160 eV; and a new broad luminescence band at an energy of 4.44 eV due to the direct radiative recombination between the genetically related electron in the states of the conduction band bottom and hole in the 4 f ground state of the Ce 3+ ion.

Description:    A method of nondestructive control of the damaged layer and roughness parameters of the surface of a hexagonal crystal and an isotropic solid with the use of Rayleigh and shear-polarized surface acoustic waves has been proposed. The surface under study borders on vacuum and can be a rough surface or an isotropic damaged surface layer. The problem is considered in the long-wavelength limit (as compared to the roughness amplitude or the thickness of the damaged layer, as well as to the characteristic radius of the surface heterogeneity). It has been shown that, in the long-wavelength limit, the dispersion of phase velocity and the damping length of shear-polarized waves can be found from the known values of the phase velocity dispersion and the damping length of the Rayleigh surface acoustic waves or vice versa. The problem for an isotropic damaged surface layer is treated in a special case where only the density fluctuates.

Description:    Lanthanum-free high-transparency ferroelectric ceramics PbMg 1/3 Nb 2/3 O 3 − x PbZr 0.53 Ti 0.47 O 3 (PMN- x PZT) have been prepared for the first time by a two-stage sintering method. The dielectric and electro-optical properties of the PMN- x PZT ceramics of different compositions, with the values of x both far from the morphotropic phase boundary ( x = 10, 16, 23%) and close to it ( x = 33%), have been studied. It has been shown that, in compositions lying closer to the morphotropic phase boundary ( x = 23 and 33%), one observes, with no electric field applied, a first-order phase transition to a macrodomain ferroelectric phase, whereas the compositions far from the boundary ( x = 10, 16%) persist in the relaxor cubic phase down to the low-temperature domain. It has been found that, in the ceramic with x = 33%, the quadratic electro-optical coefficients have at high temperatures ( T 〉 340 K) the largest value among the relaxor systems, which expands the temperature interval of applicability of these solid solutions in industry.

Description:    Small-angle X-ray diffraction from synthetic opal films has been investigated as a function of the orientation of the sample. All the observed ( hkl ) diffraction reflections have been interpreted. The reconstruction of the reciprocal lattice of the studied opal films has been carried out. The diffraction patterns and scattering intensity profiles along chains of reciprocal lattice points have been calculated. It has been shown that, in the reconstructed reciprocal lattice of the opal films, the appearance of chains of partially overlapping nodes that are oriented along the direction Γ → L is caused by two factors: the small thickness of the film and the existence of stacking faults in it.

Description:    The effect of an external magnetic field with a strength up to 140 kOe on the phase transitions in manganese arsenide single crystals has been investigated. The existence of unstable magnetic and crystal structures at temperatures above the Curie temperature T C = 308 K has been established. The displacements of manganese and arsenic atoms during the magnetostructural phase transition and the shift in the temperature of the first-order magnetostructural phase transition in a magnetic field have been determined. It has been shown that the magnetocaloric effect in a magnetic field of 140 kOe near the Curie temperature T C is equal to Δ T ∼ 13 K. A model of the superparamagnetic state in MnAs above the temperature T C has been proposed using the data on the magnetic properties and structural transformation in the region of the first-order magnetostructural phase transition. It has been demonstrated that, at temperatures close to T C , apart from the contribution to the change in the entropy from the change in the magnetization there is a significant contribution from the transformation of the crystal lattice due to the magnetostructural phase transition.

Description:    The effect of the sintering temperature from 1070 to 1670 K of ceramic samples of lanthanum manganite La 0.7 Mn 1.3 O 3 on their grain size, structure, magnetic and resistive properties has been studied. An increase in the sintering temperature to 1270 K is shown to lead to an insignificant increase in the grain size and an increase in the density, fraction of the ferromagnetic phase in a grain, and colossal magnetoresistance. The ceramics sintering at temperatures higher than 1470 K is found to sharply increase the grain size; simultaneously, the grain takes a layered structure. The grain growth at these temperatures is established to be accompanied by manganese precipitation at the grain boundaries and likely in the grain interior. The increase in the sintering temperature is accompanied by appearance of a magnetically phase heterogeneity and a decrease in the Curie temperature and magnitude of the colossal magnetoresistance effect.

Description:    The crystal structure of two-phase and porous alkali borosilicate glasses with embedded magnetic atoms has been investigated using X-ray powder diffraction. It has been shown that, during the preparation of two-phase (nonporous) glasses, the α-Fe 2 O 3 phase undergoes a transition to magnetite (Fe 3 O 4 ) with the formation (at particular concentrations of α-Fe 2 O 3 in the initial mixture) and stabilization of the β-Fe 2 O 3 phase. The characteristic sizes of nanoparticles of iron oxides (Fe 3 O 4 and β-Fe 2 O 3 ) in these glasses have been determined. For two types of porous glasses (namely, the macroporous glass Fe20-MAP and the microporous glass Fe20-MIP), the occupancies of the octahedral (Fe 2+ ) and tetrahedral (Fe 2+ /Fe 3+ ) iron positions in magnetite have been found.

Description:    Raman spectra of ZnO and core-shell ZnTe/ZnO nanowires have been measured under conditions of nonresonant and resonant excitations by Ar + and He-Cd lasers. The optical vibration frequencies that are characteristic of the wurtzite structure of ZnO crystals have been determined. The Raman-active longitudinal optical (LO) phonons in all the studied structures have a mixed A 1 and E 1 symmetry. Surface optical modes with frequencies of 460–470 cm −1 have been found. Surface optical modes of single-layer nanowires have been analyzed using the calculation performed in the previous work by P.M. Chassaing and his colleagues, and those of double-layer nanowires have been analyzed in terms of the expressions obtained in the present work. The size of heterogeneities of the nanowires along their axis has been determined.

Description:    The band structure and spectra of the total and projected densities of states of a new crystal of the chalcopyrite family, namely, CuBS 2 , have been calculated in terms of the density functional theory. It has been found that the crystal is a pseudo-direct-band-gap semiconductor, and the best theoretical estimate of the optical band gap is 3.44 eV. The upper valence band of the CuBS 2 crystal basically consists of the contributions from the p states of S atoms and the d states of Cu atoms. The crystal splitting is 0.2 eV. The bottom of the conduction band is basically formed by the sp states of boron and sulfur atoms with an admixture of the s states of copper atoms.

Description:    Microporous films of polyolefins, namely, polyethylene and polypropylene, have been prepared using the process based on the extrusion of the melt with the subsequent annealing, uniaxial extension, and thermal fixation. The influence of the conditions used for preparation of the films on their morphology, porosity, number and sizes of through-flow channels, and mechanical properties has been investigated. It has been found that a significant influence on the characteristics of the porous structure of the films is exerted by the degree of orientation of the melt at extrusion, the annealing temperature, and the degree of uniaxial extension of the films. The threshold values of these parameters, at which through-flow channels are formed in the films, have been determined. It has been shown using filtration porosimetry that polyethylene films have a higher permeability to liquids as compared to the polypropylene samples (240 and 180 L/(m 2 h atm), respectively). The porous structure of the polyethylene films is characterized by larger sizes of through pores than those of the polypropylene samples (the average pore sizes are 210 and 160 nm, respectively), whereas the polypropylene films contain a larger number of through-flow channels.

Description:    The effect of transverse entrainment of charge carriers by two electromagnetic waves propagating in mutually perpendicular directions in a semiconductor with a parabolic dispersion law has been investigated. The dc component of the electric current density that appears in the direction perpendicular to the wave vectors has been calculated in the constant relaxation time approximation. It has been shown that the transverse dc current vanishes at a particular phase difference of the incident waves determined by the relaxation time of charge carriers in the material.

Description:    The X-ray diffraction, Mössbauer, calorimetric, and magnetic characteristics of zirconolite GdFeTi 2 O 7 have been measured to determine the ground magnetic state. A kink dependent on the magnetic prehistory of the sample has been revealed in the temperature dependence of the magnetic moment at T = 3 K. Mössbauer spectroscopy has confirmed the nonequivalence of the iron ion positions in GdFeTi 2 O 7 . The experimental data obtained allow the conclusion on the formation of a spin glass state with the freezing temperature T f = 3 K in the GdFeTi 2 O 7 compound.

Description:    The crystal, local atomic and magnetic structures of Fe 75 Cr 10 B 15 alloys annealed at 440–473°C for 5 min have been studied using X-ray diffraction and 57 Fe Mössbauer spectroscopy. At the annealing temperature T a = 440°C, nanocrystals of the α-Fe phase (∼1%) precipitate in the amorphous matrix of the alloy. The complete crystallization of the amorphous alloy occurs at T a = 473°C with the formation of α-Fe nanocrystals 26 ± 2 nm in size and nanocrystals of tetragonal boride t -Fe 3 B 47 ± 2 nm in size. It has been found that chromium atoms are located in nanocrystals of the α-Fe and y -Fe 3 B types. The distribution functions of hyperfine fields in the nanocrystalline Fe 75 Cr 10 B 15 alloy reconstructed from the Mössbauer spectra (at T a = 473°C) show that there are three allowed states of iron atoms in the α-Fe phase and three equally probable crystallographic nonequivalent states of iron in the t -(Fe,Cr) 3 B phase. The chromium concentration x in the α-Fe(Cr) phase is found to be ∼10 at %. The substitution of chromium atoms for iron atoms in t -Fe 3 B substantially decreases local magnetic moments of the iron atoms.

Description:    The pressure-induced insulator-metal transition in paramagnetic sulfide BaCoS 2 at a temperature of 370 K has been described for the first time using the combination of the local electron density approximation and the dynamic mean field theory (LDA + DMFT). Based on the analysis of the spectral functions of Co 3 d orbitals, the local magnetic moments of Co, and the frequency dependence of the imaginary part of the self-energy, the existence of the insulator-metal transition for 97% of the BaCoS 2 unit cell volume at normal pressure has been established. Simultaneously, the high-to-low spin magnetic transition of Co 2+ ions occurs. Content Type Journal Article Category Phase Transitions Pages 1864-1869 DOI 10.1134/S1063783412090314 Authors V. M.

Description:    Gamma-irradiated alkali silicate glasses of the variable composition 22 x Na 2 O · 22(1 − x )K 2 O · 3CaO · 75SiO 2 have been studied using the electron paramagnetic resonance (EPR) method. It has been established that, upon the successive replacement Na → K in the two-alkali silicate glass, the EPR spectrum of hole centers on nonbridging oxygen atoms can be represented as a superposition of signals from the oxygen centers HC 1 (Na), HC 2 (Na), HC 1 (K), and HC 2 (K), which are characteristic of single-alkali silicate systems. The concentration dependences of hole and electron paramagnetic centers do not exhibit specific features that can be interpreted as a manifestation of the “mixed-alkali effect.” The results obtained have been discussed taking into account the extended model of centers on nonbridging oxygen atoms.

Description:    The possibility of fabricating a Schottky barrier on Al- p -CdTe structures with the lowest density of surface states has been demonstrated and confirmed by the results obtained from the capacitance-voltage and photoelectric measurements of the potential barrier height. It has been established that, at different forward bias voltages, there are different exponential dependences of the electric current on the voltage, which are related to the changes in kinetic parameters of the base of the Al- p -CdTe-Mo structure. It has been shown that the Al- p -CdTe-Mo structure at a forward current and high illumination levels operates as an injection photodiode. This injection photodiode has a high current sensitivity. When the current is switched on in the reverse direction, after the complete coverage of the base of the structure by the space charge, electrons responsible for the charge transfer mechanism and noise characteristics of the structure are injected from the rear contact.

Description:    The Faraday effect, light scattering, and changes in the domain structure of a single-crystal thin plate of the iron garnet Tb 0.2 Y 2.8 Fe 5 O 12 cut parallel to the (110) crystallographic plane have been experimentally investigated in the temperature range of the spontaneous magnetic orientational phase transition. It has been established that the transformation of the domain structure of the studied sample due to the orientational phase transition is accompanied by a significant temperature hysteresis. A model of the spontaneous reorientation of the magnetic moment vector of the crystal has been proposed by analyzing the results of visual observations of the domain structure and the temperature dependences of the Faraday effect and light scattering. In the proposed model, preference is given to the spin wave mechanism of nucleation of domains of the equilibrium magnetic phases.

Description:    Multilayer Fe 55 Pt 45 (20 nm)/Pt(5 nm)/Cr 100 − x W x (80 nm)/glass structures, in which the Fe 55 Pt 45 magnetic film has a face-centered tetragonal (FCT) structure of the L 1 0 phase with the (001) texture, have been prepared using magnetron sputtering. The microstructure and texture of the FePt films have been studied as functions of the W content in the Cr 100 − x W x sublayer, where 0 〈 x 〈 25. It has been established that an increase in the W ion concentration leads to the formation of the (200) texture in the Cr 100 − x sublayer and to an increase in the Cr lattice constant. This is accompanied by a decrease in the temperature at which the facecentered cubic phase transforms into the FCT phase of the FePt films as a result of the increase in tensile stresses along the a axis. It has been found that the coercivity of FePt films deposited on CrW substrates increases with increasing W content in the Cr 100 − x W x sublayer because the CrW alloy thus formed precludes diffusion between the FePt film and the CrW sublayer. An additional 5-nm-thick intermediate Pt layer is also deposited to suppress diffusion between the FePt and CrW layers. As a result, the highly textured FePt(001) films intended for ultra-high density magnetic information recording are deposited on a substrate heated to a temperature of 400°C and the Cr 85 W1 15 sublayer.

Description:    The thermal expansion of the CaCu 3 Ti 4 O 12 ceramics has been measured over a wide temperature range 120–1200 K. The high quality of the samples under study has been confirmed by good agreement of the results of measurements of the heat capacity in the range 2–300 K and in the vicinity of the phase transition of magnetic nature at 25 K with the data for the single crystal. No anomalies in the thermal expansion that can be associated with the phase transition at 726–732 K assumed by other investigators have been found. The influence exerted on the thermal expansion by the heat treatment of the sample in a helium atmosphere and in air has been investigated.

Description:    Using the equipment of the Russian-German beamline of the synchrotron radiation at the BESSY II electron storage ring, satellite spectra accompanying the C1 s core lines in the cases of single-walled carbon nanotubes and highly ordered pyrolytic graphite have been measured with a high energy resolution. The Auger spectra corresponding to shaking of the valence system of carbon by the core vacancy have been found and investigated. The Auger spectra of the studied single-walled carbon nanotubes and highly ordered pyrolytic graphite are caused by annihilation of the excited π* electron with a hole in the π subband. It has been established that the electron states in the conduction band have 3π* (gT, K, M ) symmetry; i.e., they correspond to flat 3π* subband, which is localized by 12–13 eV above the Fermi level. It has been revealed that the general regularities of the distribution of electron states in the valence system insignificantly change during its shake-up by the excited core.

Description:    The correlation functions and energy spectra of clusters of carbon nanotubes with the (5, 5) chirality that consist of 30, 50, 70, 90, and 190 atoms have been obtained in terms of the Hubbard model. It has been assumed that, taking into account the Hubbard correlations, carbon nanotubes with the (5, 5) chirality should be semiconductors with a band gap of ∼1 eV. This contradicts the generally accepted concept, according to which carbon nanotubes with the ( m, n ) chirality should be metals if the difference in the chirality indices m − n is multiple to three or equal to zero. The results obtained have been compared with experimental data on electrical conductivity and scanning tunneling microscopy of carbon nanotubes.

Description:    In alloys (solid solutions) Cd 1 − y Hg y Te enriched with CdTe, the properties of Hg-Te lattice vibrations are determined by a single-well lattice potential for the Hg atom located at the center of the anion tetrahedron. The HgTe-enriched alloys retain the anomalous properties of Hg-Te lattice vibrations, which are determined by a double-well lattice potential for the Hg atom located in the off-center position at low temperatures; a shallower well of the potential for the Hg atom located at the center of the anion tetrahedron is filled upon thermal activation. The polarizability of the ion pair in the TO mode of Hg-Te lattice vibrations with the Hg atom located at the center of the anion tetrahedron for the CdTe-enriched alloys considerably exceeds the polarizability of the pair with the off-center Hg atom for the HgTe-enriched alloys.

Description:    Expressions have been proposed for calculating the matrix elements of the Coulomb interaction of p and d electrons in a chosen ion of a crystal with an infinite crystal lattice. The matrix elements have been calculated at Gaussian-type orbitals. The Coulomb interaction energy per molecular unit of the α’-NaV 2 O 5 crystal has been calculated in the ionic approximation for homogeneous and chain orderings. It has been shown that the more correct determination of the energetic favorability of one or other ordering requires calculation of the Coulomb interaction energy with an infinite crystal lattice of electrons that are at different orbitals of the ion under consideration.

Description:    New superhard coatings based on Ti-Hf-Si-N with good physical and mechanical properties have been fabricated. A comparative analysis of the physical, mechanical, and tribomechanical characteristics of the coatings has been performed. The values of hardness, modulus of elasticity, elastic recovery, adhesive strength, friction coefficient, and wear rate of the coatings have been determined and calculated. The specific features of deformation and fracture of the coatings deposited on a steel substrate during the adhesion tests have been described. It has been shown that the parameters measured during scratching make it possible to distinguish the threshold values of the critical load, which lead to different (cohesive and adhesive) types of failure of the coatings during tribological tests. The stoichiometry for different series of samples with Ti-Hf-Si-N coatings has been determined using Rutherford backscattering, secondary ion mass spectrometry, and energy dispersive microanalysis.

Description:    The formation of annihilating pairs from molecules of aromatic compounds incorporated into the crystal lattice of n-paraffins has been studied. It has been established that annihilating pairs can be formed both from the molecules incorporated into adjacent unit cells according to the replacement principle and from the molecules incorporated with intervals of one or two unit cells of the crystal lattice of the matrix.. It has been shown that the influence of the solvent on the annihilation rate of triplet excitations of aromatic compounds is associated with the dependence of the degree of overlapping of electron clouds of interacting molecules and the distances between them on the solvent.

Description:    It has been shown that the kinetics of reactions involving mobile intrinsic defects in the crystal is described by the exponential dependence in many cases. Based on this dependence and the fact that random-walk diffusion occurs in the cases under consideration, the distribution of diffusion paths traveled by mobile defects before entering into the reaction has been found. An expression for the arithmetic mean of these paths has been obtained. For lithium fluoride crystals irradiated with gamma-rays, the pre-exponential factors in the temperature dependences of the diffusion coefficients of F 2 + color centers and anion vacancies have been determined and the diffusion coefficients of these types of defects have been estimated.

Description:    The atomic structure of single-crystal samples of Fe 1 − x Si x ( x = 0.08, 0.10) alloys has been investigated using X-ray diffraction. It has been shown that the body-centered cubic (BCC) lattice of these alloys contain clusters with local ordering of the B 2 type, which are characteristic of alloys with depleted composition ( x = 0.05−0.06). The Fe 3 Si phase with the D 0 3 structure has been revealed at silicon concentrations x = 0.08 and 0.10. The volume fraction of Fe 3 Si-phase regions increases both with an increase in the silicon concentration in the Fe 1 − x Si x alloy and during annealing of the samples with this silicon concentration at a temperature of 450°C. Based on the results obtained, it has been concluded that the anisotropic distribution of the B 2 clusters, which arises as a result of thermomagnetic or thermomechanical treatment, is responsible for the induction and stability of the uniaxial magnetic anisotropy in the Fe 1 − x Si x ( x = 0.05−0.10) alloys.

Description:    The effect of treatment at a temperature of 200°C and the natural aging on the critical parameters of a highly textured yttrium barium cuprate YBa 2 Cu 3 O 6.9 has been investigated. It has been shown that non-superconducting (at T = 77 K) particles precipitated during phase decomposition of this compound are effective pinning centers. At 200°C, the YBa 2 Cu 3 O y compound interacts with atmospheric moisture. This inter-action results in the formation of stacking faults, which also provide pinning of magnetic vortices. The structural changes occurring during low-temperature annealing and natural aging of the compound lead to an increase in the critical current density and the first critical field. The presence of pinning centers of different nature in the structure causes a synergistic effect, which significantly increases the current-carrying capacity of materials, including those in strong magnetic fields.

Description:    Spatial correlations on the surface of microporous polyethylene films obtained by extrusion of the polymer melt with the subsequent stages of annealing, uniaxial extension, and thermal fixation have been studied using scanning electron microscopy. It has been shown that, as the degree of orientation of the melt increases, the formation of the periodic superlattice of oriented lamellae occurs in the films as a result of the disorder-order transition. This transition is preceded by the formation of two mutually complementary percolation clusters, which reflect the pores and the solid phase of the polymer.

Description:    The dependences of the permittivity and electrical conductivity of TlInS 2 and TlGaS 2 single crystals on the temperature and electron beam irradiation dose have been studied. It has been established that, as the electron irradiation dose increases, the electrical conductivity σ significantly increases, whereas the permittivity ɛ decreases over the entire temperature range covered (80–320 K). It has been shown that anomalies in the form of maxima in the temperature dependences σ( T ) and ɛ( T ) are observed in the regions characteristic of phase transitions in TlInS 2 . Irradiation of the TlInS 2 and TlGaS 2 crystals with electrons to doses of 10 15 and 10 16 cm −2 does not affect their phase transition temperatures. The dispersion curves of the permittivity ɛ of the TlGaS 2 crystal have been constructed.

Description:    The magnetization of the porous glass nanocomposite with CuO nanoparticles embedded in the pores has been studied in the temperature range from 1.8 to 350 K for different pore fillings. It has been shown that the magnetic properties of these nanocomposites depend significantly on pore filling. It has been found that, in the low-temperature range for the nanocomposite with a pore filling of 55% and for pressed CuO, the ZFC and FC susceptibilities diverge, a feature which has been almost absent in the nanocomposite with 21% filling. It has been demonstrated that the kink in the temperature dependence of magnetization, which corresponds to the paramagnetic-multiferroic phase transition, does not shift in the sample with a larger pore filling as compared to that observed in the bulk sample.

Description:    This paper presents the results of the study of the influence of physicochemical parameters of thermochemical nitridation of sapphire substrates of different crystallographic orientations in an N 2 + (CO,H 2 ) reducing atmosphere on structural characteristics, composition, and kinetics of AlN layer formation. The effective diffusion coefficients of nitrogen in sapphire at T = 1473−1773 K have been determined. The temperature dependences of the structural quality, thickness, and roughness of the AlN layer surface have been found; their strong dependence on the composition and reduction potential of the nitridation atmosphere has been shown. The structural models of matching the AlN and sapphire lattices during thermochemical nitridation have been proposed.

Description:    The residual lattice strains of nanocrystals, which are responsible for the formation of states with transverse magnetic anisotropy in samples of the Fe-Si-Nb-B-Cu alloys (Finemets) subjected to annealing under tensile loading with the subsequent relaxation annealing at temperatures in the range from 500 to 600°C, have been measured using X-ray diffraction. The relative extension and compression of interplanar spacings have been compared with the induced magnetic anisotropy constants determined from the magnetic hysteresis loops. It has been shown that, during the relaxation annealing at the nanocrystallization temperature (500–540°C), the observed decrease in the residual strains is accompanied by a decrease in the transverse magnetic anisotropy constant. A linear correlation between the relative extension and compression of the interplanar spacings for different crystallographic planes and magnetic anisotropy constant has been revealed. The deviation from linearity is observed after annealing at a temperature of 600°C, which is explained by a possible increase in sizes of nanocrystals, changes in their structure, and partial crystallization of the amorphous matrix.

Description:    The structural state of a Zn 1 − x Fe x Se ( x = 0.001) crystal has been studied using thermal neutron diffraction. The diffraction patterns of the cubic crystal have been found to contain diffuse scattering regions concentrated in the vicinity of the strong Bragg reflections. It has been shown that the diffuse scattering effects are due to local transverse displacements of the crystal lattice atoms, and these displacements are induced by iron ions that demonstrate the static Jahn-Teller effect of the tetragonal type in the ZnSe compound.

Description:    The effect of temperature conditions of ion implantation on the magnetic properties of Ge 0.98 Mn 0.02 thin films has been studied. It has been shown that a decrease in the implantation temperature significantly increases the temperature of percolation magnetic ordering in the subsystem of dispersed Mn 2+ ions. It has been demonstrated that the observed effect can be due to suppression of the thermally activated aggregation of Mn 2+ ions into Ge 3 Mn 5 clusters and increase in their concentration in the dispersed state.

Description:    Our previous IR-spectrometry and thermodesorption studies of thin films of cryovacuum ethanol condensates and comparison of these data with the results obtained in works of some groups have allowed us to make several conclusions relative to temperature ranges of existence of low-temperature states of ethanol. Newly acquired experimental data indicate that the cryovacuum condensates of ethanol formed at temperatures considerably below the glass transition temperature T g ≈ 98 K pass through the state that can be characterized as a supercooled liquid phase in the course of subsequent thermally stimulated transformations. The temperature range of the solid-liquid transformation (97–100 K) agrees well with the data of researchers who studied the ethanol samples obtained by the vitrification from the liquid phase.

Description:    Alternating current resistivity measurements have been performed for the first time on intercalated Cu x HfSe 2 (0 ≤ x ≤ 0.18) samples using the impedance spectroscopy technique together with direct current measurements. The results obtained indicate the hopping mechanism of charge transport in Cu x HfSe 2 compounds. It has been found that an increase in the copper content in samples enhances relaxation processes. The ac conductivity exhibits frequency dispersion described by the universal dynamic response.

Description:    The surface morphology and local structure of layers in the Ni-Ge and Ge-Ni-Ge-Ni-Ge films have been investigated. It has been shown that the surface of the films follows the roughnesses of the substrate surface, which have characteristic dimensions of 2–4 nm in height and ∼100 nm in plane. It has been found that an interface with the depth ranging from 9 to 18 nm is formed at the boundaries between the Ni and Ge layers. The data obtained have been used to explain the specific features of the magnetic properties of the studied films, such as the asymmetry of hysteresis loops at low temperatures and the difference between the temperature dependences of the magnetization of the samples for two cooling modes: in a magnetic field and without a magnetic field.

Description:    The temperature dependence of thermal expansion of the Ti-49.8 at % Ni alloy has been measured after rolling at temperatures of 470, 570, 670, 770, and 870 K. The maximum dilatation jump during the martensitic phase transition has been observed for the samples rolled at 570 and 670 K. A fragmented structure, in which the phase transformations are hampered, is formed during the low-temperature rolling. An increase in the rolling temperature to 770–870 K leads to the return processes and dynamic recrystallization of the material; as a result, the slope of dilatation curves changes and the range of phase transitions narrows.

Description:    The history of the growth of semiconductor crystals aboard space vehicles and their subsequent investigation has been described shortly. It has been shown using Ge(Ga), GaSb(Si), and GaSb(Te) crystals as an example that the formation of segregation growth striations can be avoided during their recrystallization by the vertical Bridgman method in conditions of physical simulation of microgravity on the Earth, mainly due to the essential weakening of the thermal gravitation convection. By their structure and impurity distribution, they approach the crystals grown in space. The investigation of recrystallization of Te has made it possible to determine the role of the detachment effect characteristic of the microgravity conditions and the features of the microstructure of the samples that crystallize with a free surface. The analysis of the results obtained from experiments in space allows us to better understand the processes occurring during the crystallization of the melts and to improve the crystal growth in terrestrial conditions.
