Abstract
Anomalous low-field critical behavior was found in amorphous Fe-Mo alloys. The deviations from normal ferromagnetic behavior are exactly those recently predicted to arise from random anisotropy in an otherwise isotropic material. In disagreement with that model, however, the low-temperature susceptibility is finite. The difference in the spin-orbit coupling constants of Fe and Mo is suggested as a source of the anisotropy.Keywords
