    Notes: The magnetocrystalline anisotropy energy (MAE) of (Fe1−xCox)3P (x=0, 0.1, 0.2, 0.33) has been studied in the temperature range 5 K–300 K. The compound crystallizes in a tetragonal structure with three non-equivalent metal sites and shows an easy planar behavior with the magnetic moments aligned in the ab plane and the c axis as the hard direction. The MAE of Fe3P was investigated using magnetization measurements on a single crystalline sample. The anisotropy constants were found to be K1(approximate)−851 kJ/m3 and K2(approximate)9 kJ/m3 at 5 K and K1(approximate)−648 kJ/m3 and K2(approximate)11 kJ/m3 at 300 K. The MAE of the cobalt substituted systems was investigated on sintered samples formed into spheres. K1 for these samples was calculated from a fit of the magnetization versus internal field strength using the law of approach to saturation. © 1998 American Institute of Physics.

    A low field superconducting quantum interference device magnetometer for dynamic measurements (1997)

    Notes: A superconducting quantum interference device magnetometer system designed for low field static and dynamic susceptibility measurements is described. Magnetic shields reduce the residual field in the sample space to about 0.04 A/m (0.5 mOe). A highly stable dc magnetic field is generated by a small superconducting solenoid working in the persistent mode. The temperature control system yields a resolution better than 10 μK in the range of 30–100 K. Combining ac susceptibility and dc magnetic relaxation measurements, the system allows dynamic susceptibility studies in a time window ranging from 3×10−6to 106 s. The sensitivity of the system is 10−12 Am2 (10−9 emu). © 1997 American Institute of Physics.
