Influence of an external magnetic field on the reentrant spin-glass transition temperature in aCr75Fe25alloy

Abstract
The influence of an external magnetic field B0 on the reentrant spin-glass transition temperature TG of a Cr75 Fe25 alloy has been investigated by means of Fe57 Mössbauer-effect spectroscopy. A linear relationship in the (B0,T) plane has been observed which is interpreted theoretically in terms of a mean-field-theory model including nonvanishing local spontaneous magnetization.
