摘要：

The spin-dependent absorption of circularly polarized x rays at the K edge of Fe and the L2 and L3 edges of Gd in amorphous and crystalline GdFe2 has been studied. Large differences in the magnitude of the dichroic signal are observed between the two samples. The application of recently derived sum rules indicates substantial quenching of the orbital moment in the amorphous sample. The results are compared to a theoretical spectrum for crystalline GdFe2.
