Magnetic properties of rare earth-gallium-iron glasses

Abstract

Results of magnetic susceptibility, high‐field magnetization, and Mössbauer effect are reported for several R‐Ga and R‐Ga‐Fe metallic glasses, where R = Pr and Tb. Magnetic ordering temperatures, effective moments, and coercive forces were determined. In certain cases the data indicate that the low temperature states of magnetic order are asperomagnetic or spin‐glass‐like. For (Pr₈₀Ga₂₀)₈₀Fe₂₀, several anomalies were observed including a large coercive field (45 kOe) at 100 K.
