Kondo scattering in a pure metal- beta cerium. I. Experimental

Abstract

The electrical resistivity of DHCP beta Ce has been found to be anomalously large above 60K and to exhibit an order of magnitude drop below 20K. The magnetic susceptibility exhibits a Curie-Weiss behaviour above 40K, and magnetic ordering occurs at approximately 13K. The large resistivity is thought to be due to Kondo-like spin flip scattering which, at low temperatures, is quenched by the internal field associated with magnetic ordering.
