Abstract

Measurements of the electrical resistances of palladium and four alloys of palladium and gold have been made from liquid oxygen temperature to about 1000°C. It is found that the variation of resistance with temperature for these alloys resembles that of constantan for compositions up to about 60 atoms per cent of gold, where there is a change over to the normal type of resistance curve. This, and the results for pure palladium, are shown to be in agreement with the quantum-mechanical theory of conductivity as applied by Mott to the transition metals.
