摘要: We report here the theory of heavy fermion systems by a model Hamiltonian consisting usual Kondo lattice including an antiferromagnetic exchange interaction between nearest neighbour localized spins. The is treated in mean-field approximation that introduces two parameters: first one associated with magnetic correlation spins and second related to local effect. short range correlations parameters are obtained minimizing total energy system solved self-consistently taking into account number electrons. density states for c- f-electrons studied different system.
