Ferromagnetism and spin-glass properties ofPdFeMn

Abstract

Low-field dc magnetization measurements on the ternary allow ${\left({\mathrm{Pd}}_{0.9965}{\mathrm{Fe}}_{0.0035}\right)}_{0.95}$ ${\mathrm{Mn}}_{0.05}$ show that the decrease of the ac susceptibility below 3 K which previously had been attributed to a transition from the ferromagnetic to a spin-glass state is due simply to the onset of hysteresis in the magnetization. It is shown that the alloy remains ferromagnetic down to at least 1.8 K.
