We investigate the competition between magnetic order and local Kondo effect in a Kondo lattice model (i.e. the Coqblin-Schrieffer Hamiltonian extended to a lattice) in a mean-field approximation, taking account of the spin-orbit degeneracy Ns.o. of each localized f level. This leads to the definition of a Ns.o. dependent Kondo temperature. We study the Kondo phase and compare its energy with the...
