Abstract
Measurements of the magnetic susceptibility of AgPd alloys with Fe and Mn impurities have been performed at temperatures from 1.4 K to 300 K. Alloys with 5 and 10 at.% Pd, 2 and 6 at. ppm Fe and with Mn concentrations in the range 10 to 7,000 at. ppm were investigated. The temperature variation of the impurity susceptibility was analysed according to a Curie-Weiss law. The effective moment for Fe varies with the Pd concentration, which is interpreted as due to interactions between near neighbour Fe and Pd atoms. These interactions tend to lower the characteristic temperature of single Fe impurities and induce a spin on the Pd atom ferromagnetically coupled to the Fe spin. InAgPdMn one finds no such induced moment on the Pd atoms. The effective momentµ eff =(5.36±0.10)µ B per Mn atom and the Curie-Weiss temperatureθ=(0.08±0.09) K are independent of Pd as well as Mn concentrations.µ eff is slightly higher than for Mn in very diluteAgMn, which may be due to a different polarisation of the conduction electron gas around the impurities.
