    Notes: We have succeeded in preparing RFe10.5V1.5 compounds and their corresponding nitrides RFe10.5V1.5Nx, where R=Y, Ce, Nd, Sm, Gd, Td, Dy, Ho, and Er. The structural and magnetic properties of RFe10.5V1.5Nx have been investigated by x-ray diffraction techniques and magnetic measurements and compared with those of RFe10.5V1.5, NdFe10.5V1.5Nx is a new potential hard magnetic material with excellent intrinsic magnetic properties.

    Study of the coercivity of Pr(Mo, Fe)12Nx (1994)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: A study of the permanent magnetic properties of Pr(Mo, Fe)12Nx powders has been carried out by using a mechanical alloying technique. The variations of coercive force and remanence as a function of composition and crystallizing temperature have been investigated. A coercive force of up to 6.0 kOe was obtained. The temperature dependence of the coercive force is presented in comparison with that of Nd2Fe14B-type magnets.

    Magnetic properties of anisotropic Nd(Fe,Mo)12Nx powders (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 76 (1994), S. 1745-1748

    Notes: Anisotropic magnets based on Nd(Fe,Mo)12Nx nitrides were prepared by a milling process. Particle size dependence of the coercivity has been investigated. The optimizing size which accompanies the highest coercive force was examined by transmission electron microscopy. A coercive force iHc of up to 6.2 kOe, and a maximum energy product (BH)max of up to 12.0 MG Oe were obtained. The mechanism of the coercivities is discussed with a comparison of the powders prepared by mechanical alloying. The variation of coercive force as a function of temperature is reported.

    Thermal expansion anomalies of R2(Fe1−x Mx)14B (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 61 (1987), S. 3586-3588

    Topics: Physics
    Notes: Thermal expansion anomalies of R2(Fe1−xMx)14B (R=Nd and Y; M=Co and Al) have been observed with x-ray powder diffraction in the range from room temperature to 1000 K. All these compounds show an abnormal thermal expansion below the Curie temperature. The substitution effect of Fe by Co and Al on the thermal expansion behavior has been investigated to determine how atomic ordering of these substituent atoms influence the Fe-Fe exchange interactions so as to alter the magnetic properties of the R-Fe-B intermetallic compounds.

    Magnetic behavior and anomalous thermal expansion of Nd2(Fe1−xMnx)14B (1988)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Magnetic properties of Nd2(Fe1−x Mnx) 14B, where x equals 0.00, 0.10, 0.20, 0.30, and 0.40, are presented. All of these compounds crystallize in the tetragonal structure, space group P42/mnm. X-ray diffraction experiments in a temperature range from 77 to 800 K have been carried out in order to study the anomalous thermal expansion by measuring the thermal variation of the lattice parameters a and c. The effect of substituting Fe with Mn on the thermal expansion anomalies of Nd2(Fe,Mn)14B is discussed in comparison with that of Nd2(Fe,Al)14B and Nd2(Fe,Co)14B.

    Intrinsic magnetic properties of SmTiFe10 (1988)

    Notes: The rare-earth–iron intermetallic compounds SmTiFex, with x ranging between 8 and 10, have been synthesized by an arc-melting technique. We found that they crystallize in the ThMn12-type tetragonal structure, I4/mmm. Unusual uniaxial magnetocrystalline anisotropies have been observed. The c axis is the easy magnetization direction. Curie temperature is 610 K. After the discovery of the R2Fe14B compounds, we have other ternary rare-earth–iron intermetallic compounds with strong uniaxial anisotropy.

    High coercivity in mechanically milled ThMn12-type Nd–Fe–Mo nitrides (2000)

    Notes: Starting from carefully homogenized Nd10Fe90-yMoy (y=12, 10, 7) alloys and by appropriate mechanical milling, the as-milled microstructure consisting of a nanoscale mixture of severely distorted 1:12 phase and substitutional α-Fe-based solid solution was obtained. This kind of as-milled microstructure was thought to have a critical effect on the formation of iron-free nanocrystalline 1:12 phase during subsequent annealing. Upon nitrogenation, the sample of Nd10Fe78Mo12Nx exhibited a record-high coercivity of 13.1 kOe at 293 K. Measurements of initial magnetization curve and a family of demagnetization curves engendered under different maximum applied fields Hm were carried out, and the results revealed the domain-wall pinning at grain boundaries as the coercivity mechanism. A low Mo-content sample of Nd10Fe83Mo7Nx with iHc∼5.8 kOe, Br∼6.8 kG, and (BH)max∼7.0 MG Oe was made by optimizing the preparation conditions. © 2000 American Institute of Physics.
