Abstract
Hydrogen-amorphized GdFe2Hx were prepared for two different compositions of parent alloy and different hydrogenation temperature. The average hyperfine field grows from 22.5 T for the initial compound up to 33.4 T for the amorphized hydride. Samples amorphized at different temperatures show the same hyperfine field, whereas magnetic moment, compensation temperature and Curie temperature decrease with increasing the hydrogenation temperature. The non-Brillouin behavior of temperature dependence of magnetic moment of Gd sublattice and anomalous high-field magnetization curves were found in amorphous hydrides. The obtained results were interpreted in the assumption of heterogeneous structural state.
