Groundstate properties of the Coqblin-Schrieffer model in a crystalline field: Universality ofj=5/2 in cubic symmetry

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The Bethe-ansatz equations for the Coqblin-Schrieffer model are discussed assuming an arbitary splitting of the ionic multiplet, e.g. by magnetic and axial and cubic crystal fields. Explicit expressions for the populations of thef-levels and the static spin susceptibility are obtained for the casej=5/2(Ce3+) in a cubic environment. The universality of this solution is discussed.
