Abstract

The internal degree of freedom of the impurity atom is taken into account in calculating the anomalous part of the resistivity leading to the Kondo effect. This is achieved by adopting a generalization of the usual sβ€”d exchange interaction, first proposed by Vonsovskii and Svirskii. We find that, if the intra‐atomic exchange interaction is neglected, the logarithmically divergent character of the anomalous part of the resistivity is retained with an effective coupling strength. It is argued that the inclusion of the intra‐atomic exchange term may affect the logarithmically divergent character of the conduction electron scattering amplitude near the Fermi surface.

We have studied the one-dimensional Kondo chain at half-filling using a density matrix formulation of the numerical renormalization group. As the exchange coupling J --. 0, RKKY interactions become more important, and the correlation length and the staggered susceptibility x(q = 2kv) diverge.

Recent inelastic neutron scattering experiments on CeSi, (x=1.7, 1.8, 1.85. 1.9) ate reported. We discuss the origin of the cmssover transition from a Kondo-like state to a magnetically ordered state in this system by taking account of the experimental results.
