Perturbation theory for the Green's functions of the Heisenberg model with single-ion anisotropy
A. A. Kazakov
Abstract:
Instead of solving the set of the $2S$ equations for Green function of ferromagnetic
with the single-ion anisotropy, it is suggested to solve a single equation for the parametric
Green function. The solution of this equation is used for exact calculation of
ferremagnet magnetization of spin $S=1$ with one and two sublattices. The approximate
solution is found for arbitrary value of the spin.
