摘　　要：本文通过对非晶态轻稀土Pr,Nd和过渡族金属Fe,Co,Ni薄膜合金的低温磁性研究,分别得到了(Pr,Nd)_x-(Fe,Co,Ni)_(1-x)合金中Pr,Nd和Fe,Co,Ni金属磁矩随成份x的变化,并且通过对磁矩的研究得到Pr离子的4f电子可能有退局域化的结论。Through the investigation of the low temperature magnetic properties for the amorphous light rare-earth (Pr, Nd) and transition metal (Fe, Co, Ni) alloy thin films, the composition dependence of the magnetic moment for each of Pr, Nd, Fe, Co and Ni atoms in these alloys can be determined. We found that the delocalization of 4f electron of Pr atom may be studied by analyzing the variation of the magnetic moments of the Fe, Ni and Pr atoms with presence of the Pr component.
