Sažetak
The magnetic susceptibility and susceptibility anisotropy of the quasi-binary alloy system CexLa(1-x)Cu2.05Si2 have been studied for low concentration of Ce ions.The single-ion description is found to be valid for x<=0.09. The experimental results are discussed in terms of the degenerate Coqblin-Schrieffer model with a crystalline electric field splitting Delta = 330 K. The properties of the model, obtained by combining the lowest-order scaling and the perturbation theory, provide a satisfactory description of the experimental data down to 30 K. The experimental results between 20 K and 2 K are explained by the exact solution of the Kondo model for an effective doublet.
