摘要：

The diluted anisotropic Heisenberg ferromagnet is considered in the pair approximation. The structural short-range-order, described by the Warren-Cowley parameter, is taken into account. In the presence of interaction anisotropy, the influence of dilution and structural correlations on the phase diagrams is studied. In particular, for the model in question the critical concentrations and Curie temperatures are calculated for exemplary two-dimensional and three-dimensional lattices.
