Magnetic properties of amorphous Y-Ni alloys

Abstract

Y_xNi_1−x amorphous alloys are shown to behave as weak itinerant ferromagnets. The model of Edwards and Wohlfarth allows for a satisfactory understanding of their major properties. However, discrepancies with this model lead us to analyse our results in the light of recent theories of itinerant ferromagnetism. Satisfying agreement is found.
