Abstract

In order to obtain information on the nature of spin coupling in Fe-rich alloys, we performed high-precision57Fe Mössbauer effect and magnetizations measurements in a wide temperature range. These results show that with increasing temperature amorphous Fe90Sc10 alloys undergo a transition from a cluster spin-glass to superparamagnetism followed by paramagnetism.
