Abstract

The magnetic properties (such as the saturation magnetization, the exchange stiffness constant, the local magnetic anisotropy field, the ferromagnetic resonance linewidth) of fine Co-P particles with different phosphorus concentration and particle sizes have been studied. The powders have been prepared by chemical reduction. The particle size was in the range of 0.1-3 μm. The structure of these powder dominate the magnetic properties. The maximum saturation magnetization obtained for these particles is approximately 1000 G. The FMR linewidth was found to depend on the local magnetic anisotropy of the particles for all phosphorus contents
