Abstract The doped anisotropic antiferromagnet, which is believed to describe the elementary properties of the high-temperature superconductors, is studied by making use of Green’s function theory of the t-J model. The Néel transition and staggered magnetization dependence on the anisotropic parameter ς and the doping density δ in La_2-δSr_δCuO₄ are obtained. These results are found to be in good agreement with experiments on the cuprates.
