| Popis: | The ground-state magnetic phase diagram is calculated within the two-dimensional Anderson lattice model by employing a generalized Hartree-Fock approximation for the spiral magnetic ordering, as well as collinear one. The first-order transitions between different types of magnetic order are treated consistently, which allows one to describe the ''magnetic" phase separation. The features of magnetic order for the cases of integer and intermediate valence turn out to be substantially different. In the corresponding particular cases, the results are in a qualitative agreement with those for the s-d exchange and Hubbard models. |
