Abstract

The Mössbauer measurements performed on Fe100−x Gd x thin films and on Fe80−x Gd x B20 both as thin films and ribbons show a dependence of the spins orientation and 〈Hhyp〉 versus temperature, Gd content and preparation conditions. Increasing the Gd content, the initial low anisotropy disappears and 〈Hhyp〉 decreases. A sharp increase of the anisotopy with temperature in ribbons with low Gd concentration is evidenced.
