摘要：

We discuss the formation of ordered phases at low temperatures in the Falicov-Kimball model within the Bethe-Peierls approximation and in second order perturbation in the coupling Ufd and an exchange J. The groundstate may be paramagnetic, ferromagnetic, ferromagnetic or antiferromagnetic, as well as charge-ordered. © 1979.
