Abstract:
Interaction effects between solute atoms in some alloy systems have been-studied by magnetisation, susceptibility and resistivity measurements. The design and construction of a vibration magnetometer built for the magnetisation and susceptibility measurements is described in detail. The resistance measurements were made using standard potentiometric techniques. The systems investigated are the Rh based alloys of Fe and Co and the gold-rare earth alloys. Measurements on Rh-Fe alloys have been made to study the effect of the formation of the quasi-bound state on the onset of magnetic order in the alloys. This onset is indicated by clearly defined maxima in the susceptibility and anomalies in the resistance near the temperatures of the maxima for alloys with more than 3 at.% Fe. Cooling the alloys in a magnetic field produces displaced magnetisation curves indicating a distribution of internal fields that can be disturbed by an applied external field. The high temperature susceptibility of the alloys is interpreted in terms of a large temperature independent contribution and a temperature dependent term obeying Curie law.
