Magnetic Susceptibility of Dilute Cu Alloys at Low Temperatures

Abstract

The temperature dependence of the magnetic susceptibility of a number of dilute copper-tin and copper-iron alloys has been measured between room temperature and 4.2\ifmmode^\circ\else\textdegree\fi{}K. The results indicate an anomalous paramagnetism in the neighborhood of the temperature of the observed resistance minimum in these alloys. Proposed models for the resistance minimum and impurity scattering are reviewed in the light of this new magnetic information.
