Abstract:
A mixed technique which combines the electronic band structure and the Anderson model is employed to study CeM2Si2 compounds (M=Ru, Rh and Pd). The Kondo physics is obtained by solving this model within an extended non-crossing approximation; the outcoming crystal-field splittings and spectral properties are in good agreement with existing experimental results. © 2005 Elsevier B.V.
