Abstract
We describe here in the mean-field approximation, a Kondo lattice mode l including nearest-neighbour magnetic exchange. In the case of antife rromagnetic correlations, our model yields a decrease of the Kondo tem perature compared to the impurity value and the appearance of short-ra nge magnetic correlations at a temperature clearly larger than the Kon do temperature, as observed in several cerium compounds.
