Impurity Resistivity in Platinum

Abstract

Measurements were made of the resistivity due to nonmagnetic transition metal impurities in Pt to study its dependence on the valence difference Δz between impurity metal and Pt. The results are consistent with the results of band-theoretical calculation for the effect of nonmagnetic impurities in Pd, i.e. for impurities with small Δz a virtual bound state is formed in the continuum and for those with large Δz a bound state above the Fermi level.
