The thermal and magnetic properties of palladium-silver alloys

Abstract The magnetic susceptibilities of a series of palladium-silver alloys from pure palladium to approximately 50 atomic % silver, have been measured over a range of temperature from 20 to 290° K. The specific heats of a similar series of alloys have been measured in the temperature range 11 to 20° K, and the results used to deduce the electronic specific heats. Owing to the variation of the Debye characteristic temperature with temperature these values are not considered to be of high precision beyond 15% silver content. Making a reasonable correction, however, it has been possible to deduce the band form for palladium. By extrapolation of the susceptibility results to 0° K the variation of Stoner’s exchange interaction parameter with concentration has been investigated over a limited range.
