Abstract
We have studied the effect of random magnetic anisotropy (RMA) on transition behavior in Gd-Co glasses. The large RMA induced by alloying with anisotropic rare-earth elements produces standard speromagnetic behavior which includes nonsaturation of magnetization at large enough concentrations at 4.2 K and high fields in all the alloys except the most concentrated Tb alloys. Although these latter alloys have the largest coercivity and the strongest RMA they appear to be closer to saturation at high fields than intermediate concentration Tb alloys. We discuss a mechanism by which this saturation may be produced by short-range correlations in the anisotropy axis.This publication has 7 references indexed in Scilit:
