Abstract
The magnetic properties associated with the spin auctuation of YxNiioo-x (8:Xs32.5) amorphous alloys are investigated. The temperature dependence of Magnetization for YioNigo and Yi4Nis6 amorphous alloys exhibits a T4/3--M2 relation below the Curie temperature, as expected from the self consistent renormalization (SCR) theory. The reciprocal magnetic susceptibility shows a temperature dependence similar to that of the temperature-induced localized moment caused by the saturation of increasing amplitude of the local spin density,. The starting temperature of the saturation of 2L is estimated to be T“=230 K. The saturation of has also been conhrmed by measuring the thermal expansion.
