N2 - The underscreened Kondo lattice model presented here includes both an intra-site Kondo exchange interaction JK between the conduction band and localized 5 f electrons described by S = 1 spins, and an inter-site exchange f- f interaction JH. We write both localized and itinerant spins in a Fermionic representation, and then use a mean-field approximation. We obtain a coexistence of Kondo effect and magnetism which can account for the behavior of some Uranium compounds.
