中文摘要This paper describes a method to calculate the three components of statistical average of spin operators with Heisenberg model when the exchange interaction is anisotropic in z direction. By the use of many-body Green's function method, when external field is applied in both x and z directions, formalism for calculation of magnetization and are explicitly derived for spin value S=1/2, 1, 3/2, 2, and 5/2. Based on the formalism, a general expression for calculation of for any spin value is suggested. Numerical analysis is presented for both cases of isotropic and anisotropic exchange interaction. The results of both three-dimensional and two-dimensional cases are discussed. Based on the numerical results, we suggest a method to test a film in experiments whether there is an ingredient of exchange anisotropy.
