摘 要:We report studies of precise magnetization measurements on amorphous GdT(T=Co,Ni and Cu) alloys between 4.2 K and 300 K under a magnetic field of 5.0 T.A form for temperature changes in magnetization is proposed from the viewpoint of fluctuations of the local magnetic *** magnetization of the amorphous GdNi and GdCu ferromagnets obeys the simple spin wave T *** the amorphous QdCo alloy,on the other hand,we have found the Stoner-type T contribution to the magnetization as well as the spin wave T term.
