The magnetization and Curie temperature of rapidly quenched (Gd0.7M0.3)80Si12B2 (M=Y, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Al) amorphous alloys were investigated. The Curie temperatures of alloys with M=Mn, Fe are higher by about 70K and 120K than that of Gd80Si12B8 amorphous alloy. The magnetic moments of Mn, Fe and Co atoms are 2, 1 and 1µg respectively. These magnetic moments are antiparallel to that of the Gd atoms. The magnetic moment of Ni atoms nearly disappears; the magnetic moments of Y and V atoms are 1.7 and 2.1µB respectively. The magnetic moment of Y atoms is antiparallel to that of Gd atoms, while that of V atoms is parallel to the latter. We conclude that alloys with nonmagnetic elements M exhibit asperomagnetism in which the Gd moments are distributed, while alloys with magnetic elements M have a ferrimagnetic order.
