摘要：

Magnetization Curie temperature and magnetovolume effects of amorphous (GdxFe1-x)80Si12B8 alloys (0.1 less-than-or-equal-to x less-than-or-equal-to 1.0) were investigated. Gd80Si12B8 is an asperomagnet having the Curie temperature of 129 K. The large susceptibility of the asperomagnet enhances the forced volume magnetostriction for x more than 0.7, which reaches about 100 X 10(-10) Oe-1 at x = 1.0 and T = 30 K. The Mossbauer study revealed a decrease of the Fe magnetic moment with an increase of Gd content. Exchange interactions J(FeFe) and J(FeGd) evaluated by the fitting of sigma-T curves are discussed and compared with those of crystalline GdFe compounds.
