摘要：
Magnetization and Cude temperature of amorphous Fe80-XErXB12Si8 alloys (0 less than or equal to X less than or equal to 15) were investigated. The Er moment is 8.2 mu(B) at 4.2 K, which indicates a conical spin structure. The mean field theory has been wed to explain the temperature dependence of the magnetization. This analysis yields the spin values of Fe and the effective exchange interaction between Fe-Fe and Fe-Er atom pairs, which are then correlated with the Fe moment.
