The Green's function theory of the t–J model is generalized to investigate phase diagram and magnetic properties of the doped anisotropic antiferromagnet, which is believed to describe the elementary properties of the high-temperature superconductors. Antiferromagnetic–metalic phase transition is shown. The explicit dependence of the Néel temperature and sublattice magnetization of the anisotropic doped antiferromagnets on anisotropic parameter ς, doping density δ and parameters of the t–J model are obtained for small doping concentration.
