Anomalous Electron-Phonon Resistivity of Metals Containing Magnetic Impurities

Abstract

The electron‐phonon contribution to the resistivity of a metal containing a small concentration of impurity atoms is strongly enhanced over its value for the ideally pure metal if the conduction electron lifetime for impurity scattering varies with energy on a scale comparable to, or less than, the Debye energy of the metal. We present a working formula for this effect and briefly describe some important consequences for metals containing magnetic or nearly magnetic transitional impurities.
