    Notes: By means of x-ray phase analysis, it is shown that all the interstitial Sm2(Fe1−xAlx)17Ny nitrides and the parent compounds crystallize in Th2Zn17-type structure for x≤0.4. The lattice constants of the parent compounds increase linearly with Al concentration. The introduction of nitrogen leads to a further increase in lattice constants, but the amplitude of the increase decreases with increasing Al concentration. The introduction of nitrogen leads to an increase of Curie temperature Tc . The composition dependence of Tc of the parent compounds exhibits a maximum, whereas Tc of the nitride decreases monotonously with increasing Al concentration from 750 K for x=0 to 313 K for x=0.4. The mean magnetic moments of iron ions in both nitrides and parents decrease monotonously with increasing Al concentration.

    A study on the exchange interaction in R2Fe17 compounds (1996)

    Notes: A study on the exchange interaction in R2Fe17 compounds (R represents the heavy rare earth elements) has been performed by means of a mean-field analysis of the high-field magnetization curves, which were measured on the powder samples. Measurements have been carried out on R2Fe17-based quasiternary R2Fe17−xMx compounds with R=Dy, Ho, and Er, M=Al, Ga, and Si. It has been found that the value of the exchange coupling constant decreases with increasing atomic number of R ion of the compound. This behavior is explained by the varying 4f–5d hybridization in the compounds. © 1996 American Institute of Physics.

    Metamagnetic transition in PrCo13−xSix (1996)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Alloys of PrCo13−xSix (1.5≤x≤4.0) have been prepared by arc melting and subsequent annealing. X-ray powder diffraction proved that the alloys crystallized in the cubic NaZn13-type structure for x=1.5, and in the tetragonal NaZn13-derivative one for x≥2.0. Their Curie temperatures are almost independent of the Si content. Their magnetization curves exhibit a binary-step characteristic. The ac susceptibility curve indicates that there exists a magnetic transition below room temperature. The anomalous binary-step magnetization curves and the ac susceptibility curves versus temperature suggest a metamagnetic transition. © 1996 American Institute of Physics.

    Magnetic properties of Sm2(Fe1−xGax)17 (x=0−0.5) compounds and their nitrides : The 6th joint magnetism and magnetic materials (MMM)−intermag conference (1994)

    Notes: Magnetic properties of Sm2(Fe1−xGax)17 compounds and their nitrides have been studied. Substitution of Ga for Fe leads to an increase in lattice constants. Introduction of nitrogen results in a further increase in lattice constants. Substitution of Ga for Fe causes a dramatic change of the Curie temperature of the Sm2(Fe1−xGax)17 compounds. When x=0.2 the Curie temperature is enhanced by about 200 K. X-ray-diffraction patterns of aligned samples of Sm2(Fe1−xGax)17 compounds show that alloys with x=0.15, 0.20, and 0.25 exhibit uniaxial anisotropy at room temperature. The introduction of nitrogen made the samples with x≤0.4 exhibit uniaxial anisotropy at room temperature. The Curie temperature of the nitrides decreases with the Ga concentration. The anisotropy fields of the nitrides derived from the high-field magnetization. The changes of the magnetic anisotropy, saturation magnetization, and the moment of the Fe atoms in the nitrides and their parent compounds with Ga concentration are discussed.

    Structure and magnetic properties of rapidly quenched (NdPr)-Fe-(BC) alloys (abstract) : 35th annual conference on magnetism and magnetic materials (1991)

    Notes: It had been reported that substitution of C for B enhances the magnetocrystalline anisotropy of Nd2Fe14B1−xCx compounds.1 This paper will study the structure and magnetic properties of (NdPr)15Fe77(B1−xCx)8 alloys changing with x=0, 0.1, 0.2, 0.3, 0.4, 0.6, 0.8, 0.9, and 1.0. It is found that the Curie temperature and welting point of the (NdPr)15Fe77(B1−xCx)8 alloy decrease linearly with increasing C content, indicating that B can be replaced by C continuously (x≤0.9). (NdPr)2Fe14X (X=BC or B1−xCx) phase which maintains the Nd2Fe14B-type structure is formed in quenched ribbons (x≤0.9), and (NdPr)2Fe17Cx with the Th2Zn17-type structure and Nd2C3 phase are formed in the ribbon of x=1. The substitution of C makes the grains fine and homogenized. The best effect of fining grains (size (very-much-less-than)0.1 μm) is obtained in the ribbon for x=0.6, and the values of Ms, Br, i Hc, and (BH)max are 12.5 kG, 7.04 kG, 18.5 kOe, and 8.79 MGOe, respectively (maximum field of 70 kOe). This subject was partly helped by the Magnetism Laboratory of Institute of Physics, Academia Sinica.

    Notes: Magnetocrystalline anisotropy, Curie temperatures, spin reorientation temperatures, and first-order magnetization processes (FOMP) are reported for RFe10Si2 compounds with R=Y, Gd, Tb, Dy, Ho, Er, and Lu. The saturation magnetizations of them at 1.5 K are determined. The value of the R-Fe magnetic-coupling constant JRFe/k, derived by a mean-field analysis of the Curie temperatures, is about −10 K. A tentative spin-phase diagram for the RFe10Si2 series is presented.

    Notes: Nd3(Fe,Ti)29−xCox compounds with Nd3(Fe,Ti)29-type structure have been synthesized with x=0, 1.61, 3.22, 4.83, and 6.44. The easy magnetization directions of all these compounds are found to be in the basal plane. The Curie temperature increases strongly with increasing Co content. Substitution of Co for Fe leads to a monotonic increase of the saturation magnetization. The spin reorientation transitions are found for all of these compounds, and the spin-reorientation temperature decreases with increasing Co content. © 2000 American Institute of Physics.

    Notes: The temperature dependence of the magnetic susceptibility, the magnetization at 4.2 K in fields up to 35 T, and the specific heat between 1.3 and 40 K in fields up to 5 T of the ternary Ce intermetallic compounds CeCuX (X = Si, Ge, Sn) have been studied. All three compounds form in ordered ternary structures related to the hexagonal AlB2 type. Ferromagnetic order is found below 14.9 K for CeCuSi and below 10.2 K for CeCuGe. The magnetic order of CeCuSn below 8.6 K is of antiferromagnetic type but probably complex, as indicated by a double peak in the specific heat and the occurrence of a very low zero-field moment.

    Magnetocrystalline anisotropy of TbFe12−xTix single crystals (2000)

    Notes: TbFe12−xTix single crystals have been investigated by means of magnetic measurements. With decreasing temperature, a spin-reorientation transition from easy axis to easy plane occurs. The rate of decrease of spin-reorientation temperature with x is about −380 K/Ti. There exists a strong magnetocrystalline anisotropy in the basal plane. The anisotropy field Ba between [100] and [110] for the compound TbFe11.15Ti0.85 is as high as 35 T which is about three times Ba in the axial direction. With increasing x, the easy magnetization direction at low temperatures in the basal plane changes from [110] for x=0.85 to [100] for x=1.0. The composition dependence of anisotropy can be understood in terms of a change of the crystal field parameters Anm due to substitution of Ti for Fe. © 2000 American Institute of Physics.

    Structure and magnetic properties of Gd3(Fe1−xCox)25Cr4 compounds (1999)

    Notes: The structural and magnetic properties of Gd3(Fe1−xCox)25Cr4 compounds with x=0–0.6 have been investigated. The structures of all the compounds investigated are found to possess monoclinic symmetry and belong to the A2/m space group. Substitution of Co for Fe leads to a clear contraction of the unit-cell volume. The Curie temperature increases from 492 K for x=0 to 762 K for x=0.6. The composition dependence of the saturation magnetization at 5 K reaches a maximum around x=0.3. It is noteworthy that substitution of Co for Fe results in a significant change of the magnetocrystalline anisotropy of the Co sublattice, and changes the easy magnetization direction of Gd3(Fe1−xCox)25Cr4 compounds from basal plane to easy axis. © 1999 American Institute of Physics.
