摘要
The thermoremanent and isothermal remanent magnetization of (La1-xGdx)Al2, as well as its time, temperature, magnetic field, and concentration dependence have been studied. The saturated remanent magnetization σrs follows scaling laws up to x=4 at.% Gd. The general relation between time and temperature dependence of σrs, based on a model of spin regions, is shown to hold in this system. An explanation for the occurrence of a maximum in the field dependence of the thermoremanence is suggested. © 1979 The American Physical Society.
