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. Journal of Applied Physics is copyrighted by The American Institute of Physics.
