    Notes: Co–P powders were produced by chemical reduction. The powders had a spherical shape with an average diameter of about 1 μm. X-ray diffraction and differential scanning calorimetry studies confirmed that the powders were amorphous. The amorphous powders showed higher saturation magnetization than the crystalline counterparts. Heat treatment of the powders above the crystallization temperature resulted in the formation of fcc Co, hcp Co, and Co2P phases. The saturation magnetization of the annealed powders monotonically decreased as the annealing temperature increased. On the other hand, the coercivity of the annealed powders rapidly increased with increasing annealing temperature. The powders annealed at 600 °C had a saturation magnetization of 100 emu/g with a coercivity of 500 Oe. © 2000 American Institute of Physics.

    Ferromagnetic Mn/C/Si films (1995)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Ferromagnetism at room temperature has been found in Mn/C/Si films prepared by sequential deposition of these elements at a substrate temperature about 360 °C by vacuum evaporation. The saturation magnetization increases rapidly with the carbon quantity, and it is about 250 emu/cc for a film with a nominal structure of Mn(6 nm)/C(0.5 nm)/Si(6 nm). The magnetization measurements at low temperatures show that the magnetic moment per ferromagnetic Mn atom corresponds to more than 1.2 Bohr magnetons. © 1995 American Institute of Physics.

    Anomalous Hall resistivities of single-crystal Fe16N2 and Fe–N martensite films epitaxially grown by molecular beam epitaxy (1998)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The anomalous and ordinary Hall resistivities for Fe16N2 (saturation magnetization 4πMs: 29 kG at room temperature) and Fe–N martensite (24.8 kG) films have been measured in the temperature range from 30 to 300 K and compared with pure Fe (21 kG) films. All films were epitaxially grown on GaAs(001) substrates by molecular beam epitaxy. The saturation anomalous Hall resistivity ρAS for Fe16N2 at 300 K was 4.0×10−7 V cm/A which was much higher than the values for Fe–N martensite (1.9×10−7 V cm/A) and Fe (1.5×10−7 V cm/A). Also the anomalous Hall constant RA at 300 K for Fe16N2 was 1.5×10−11 V cm/A G, which was much higher than the values for Fe–N martensite (0.8×10−11 V cm/A G) and Fe (0.7×10−11 V cm/A G). Such results are consistent with a much larger magnetic moment for Fe16N2. To investigate the consequences of the giant magnetic moment for Fe16N2 as compared with Fe–N martensite and Fe, the temperature dependences of ρAS and RA were measured. The values of ρAS and RA decreased monotonically with decreasing temperature for Fe16N2, Fe–N martensite and Fe. In the temperature range from 30 to 300 K, the ρAS value for Fe16N2 was much higher than the values for Fe–N martensite and Fe. This originated from the larger thermal fluctuation of the magnetization for Fe16N2. The striking features of Fe16N2 magnetism were its giant magnetic moment and its large thermal fluctuation of the magnetic moment. The electrical resistivity at room temperature for Fe16N2 was around 30 μΩ cm as compared with 10 μΩ cm for Fe. The difference was due mainly to the difference in the residual resistivities. The electrical resistivity for Fe16N2 decreased monotonically with decreasing temperature, which is normal for a metallic material. © 1998 American Institute of Physics.
