    Soft magnetic properties of nanocrystalline FeRuGaSi-Hf alloy films and head characteristics for the embedded thin film tape head : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: The Hf-added FeRuGaSi alloy film has an amorphous structure in the as-deposited state and becomes nanocrystalline after annealing. Due to this structure change from crystalline to amorphous by the addition of Hf, soft magnetic degradation of the film deposited on the slant grooved substrate, which is necessary for the sophisticated embedded thin film (ETF) head structure, is greatly suppressed and the undesirable film stress is relieved. The FeRuGaSi-Hf alloy film has higher resistivity and permeability at high frequencies than those of sendust film, and the read/write characteristics of this alloy film show better performance than sendust film. © 1996 American Institute of Physics.

    Temperature dependence of reflectance and transmittance at 514.5 nm of CdS films formed by laser ablation (1996)

    Notes: The temperature dependence of reflectance and transmittance of a thin (2 μm) CdS film prepared by laser ablation was investigated. The measurements were performed with the 514.5 nm line of an argon laser in the range 180–350 K. It occurred that due to locally enhanced absorption at the film/substrate interface, the transmitted light was considerably weaker than would be theoretically expected for a homogeneous layer. The reflectance, however, followed the theory based on Urbach's rule. The interfacial enhancement of the absorption was confirmed by luminescence investigations. © 1996 American Institute of Physics.

    Electric field dependent intersubband optical transitions in a ZnCdSe–ZnSe superlattice (1996)

    Notes: The polarization dependence of the excitonic transition in ZnSe-Zn0.8Cd0.2Se superlattices was studied by low-field electroreflection spectroscopy. A new peak observed in the lower energy side of the n=2 heavy-hole exciton E2hh at room temperature is attributed to the forbidden transition in zero field from the n=2 heavy-hole state to the n=1 electron state. This reflection change is found to be polarization dependent. © 1996 American Institute of Physics.

    Depth profile and lattice location analysis of Sb atoms in Si/Sb(δ-doped)/Si(001) structures using medium-energy ion scattering spectroscopy (1999)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: Medium-energy coaxial impact-collision ion scattering spectroscopy has been used to study the depth profile and lattice location of Sb atoms in Si/Sb(δ-doped)/Si(001) structures prepared by solid phase epitaxy. The Sb atoms are observed to diffuse into the Si capping layer at concentrations much higher than the solubility limit in a Si crystal. In addition, the concentration of diffused Sb atoms does not show a monotonic decrease with increasing distance from the δ-layer plane. The lattice locations of the diffused Sb atoms are found to be strongly dependent on the distance from the location of the original Sb δ layer. © 1999 American Institute of Physics.

    Surface-acoustic-wave properties of MgO-doped LiNbO3 single crystals measured by line-focus-beam acoustic microscopy (1999)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 85 (1999), S. 7863-7868

    Notes: Basic acoustic properties of five MgO-doped LiNbO3 rectangular parallelpiped specimens, having X-, Y-, and Z-cut planes, with different MgO dopant concentrations ranging from 0 to 13 mol % are investigated by line-focus-beam acoustic microscopy. The investigation is conducted to characterize the optical-use MgO:LiNbO3 crystals and wafers and to establish large-diameter crystal growth conditions. Leaky-surface-acoustic-wave (LSAW) velocities are measured on each crystalline plane of each specimen as a function of the wave propagation direction and are compared with the measured chemical composition ratios of Mg/Li/Nb, densities, and lattice constants. It is shown that, as the dopant concentrations increase in the experimental composition region, the LSAW velocities increase almost linearly for all the surfaces and all the propagation directions. The LSAW velocities are linearly proportional to the lattice constants, but inversely proportional to the densities. © 1999 American Institute of Physics.

    Femtosecond phase spectroscopy of multi-level systems: Phthalocyanines (1996)

    Notes: Abstract.  A femtosecond frequency-domain interferometer is applied to metal-free and vanadyl phthalocyanine (H2Pc and VOPc) thin films to measure time-resolved difference phase and transmission spectra simultaneously. For both samples, the phase-change dynamics is different from the transmission-change dynamics at 620 nm, reflecting that the phthalocyanines (Pc) cannot be modeled with a two-level system but by a multi-level or inhomogeneously broadened system, in which each level pair exhibits different relaxation dynamics. Because of this dynamical difference, a phase-change measurement is required to correct distortion of the transient spectra due to induced phase modulation of probe pulses. Near zero time delay, the phase and transmission changes show different growth behavior. This behavior is explained by antisymmetric amplitude and phase gratings which are produced by coherent coupling between frequency-chirped pump and probe pulses.

    Study of pulsed laser deposition of RuO2 and SrRuO3 thin films (1999)
    Springer
    Applied physics 69 (1999), S. S587

    Notes: Abstract. In this study, the pulsed laser ablation of RuO2 and SrRuO3 (SRO) is investigated by observing the fluorescence from excited atoms in the plume by using a framing streak camera. Vaporization, phase explosion and boiling are suggested to play the main roles in the processes for the interaction between the laser beam and target. Collisions and adiabatic expansion are also suggested before particles move forward with shifted Maxwellian spatial distribution. In O2 pressure, numerous collisions between fast and slow atoms occur and result in the exchange of speeds. The structural and electrical (conductivity and work-function) properties of RuO2 and SRO thin films are measured. Epitaxial SRO growth was obtained at growth temperatures down to 350 °C. Ferroelectric and high- dielectric thin-film capacitors with RuO2 or SRO thin film electrode are also studied.
