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.
