Limited ferromagnetism and other magnetic properties of Pd-Mn alloys

Abstract

Solid solutions of Mn in Pd have been studied by magnetization, paramagnetic resonance and electrical resistivity measurements and have been found to yield ferromagnetism only for solute concentrations below 5% and temperatures below 8K. At higher concentrations a susceptibility maximum and other effects characteristic of spin glass ordering appear, and in the transition region there is evidence for a large amount of freezing of spin entropy of a less well defined character. This behaviour is discussed in terms of the roles of solute-solvent interactions and solute-solute interactions for close and distant neighbours.
