Effect of Crystal Field on Kondo Resistivity in Ce Compounds

Abstract
The effect of crystal field on Kondo resistivity in metals with Ce impurities is theoretically studied. The T -matrix of conduction electron is calculated in the self-consistent ladder approximation by applying Abrikosov's pseudofermion technique to the Coqblin-Schrieffer exchange model. The numerical results of the resistivity in cubic and tetragonal crystals are compared with the experimental ones in Ce x La 1- x Al 2 and CeCu 2 Si 2 . Our theory provides a unified view of the magnetic and transport properties in Ce compounds and alloys.
