Abstract

Magnetization measurements on amorphous Gd_0.33Co_0.67 films indicate that T_c is>30 per cent higher in the films than in the ordered compound, GdCo₂, of the same composition. This reverses the trend observed in isostructural Tb_0.33Fe_0.67 and many other amorphous ferromagnets, where T_c is lower in the amorphous state. A qualitative explanation of the effect of structural disorder on magnetic properties of the Co and Fe compounds is given in terms of the consequences of charge transfer to the transition metal atoms.
