摘要：

The resonance characteristics (inhomogeneous FMR linewidth Delta H) in highly dispersed (d=0.1-3 mu m) powders of crystalline and amorphous Co-P alloys are investigated as a function of the composition, particle size, and atomic structure. It is established that Delta H for powders of amorphous Co-P alloys is two to three times larger than Delta H for crystalline Co-P powders. According to the investigations performed, this is caused by thermodynamically stimulated segregation of nonmagnetic Co2P inclusions, apparently an effective relaxation channel, in the amorphous state of Co-P powders.
