“…16͒ or CeNi x Pt 1Ϫx , 17 are not really relevant for our present study since the experimentally observed transition to nonmagnetism corresponds probably here to a change of valence. 18 This type of transition to an intermediate valence has been also observed in alloys such as Ce͑Cu x Pd 1Ϫx ) 2 Si 2 ͑Ref. 19͒ or CeM x Pd 1Ϫx ͑with M ϭ Ni or Rh͒.…”

The Kondo lattice model including nearest-neighbor magnetic exchange interactions is studied here in a mean-field approximation describing both the Kondo state and the intersite magnetic correlations. In the case of antiferromagnetic correlations, our model yields a decrease of the Kondo temperature compared to the one-impurity value, giving, therefore, a ''revisited'' version of the Doniach diagram with a rather flat Kondo temperature in the nonmagnetic case, as observed in several cerium compounds. Our model shows also that short-range magnetic correlations can appear at a temperature clearly larger than the Kondo temperature, as observed in compounds such as CeCu 6 or CeRu 2 Si 2 . ͓S0163-1829͑97͒04642-0͔
