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.
