摘要：
The susceptibility is studied by the inversion method, which advances the Stoner theory systematically. This is because the method is a kind of perturbation theory and its first order calculation reproduces the mean-field theory. The second order of the inversion method is applied for the concrete model for the first time. It is possible to realize the Curie-Weiss law and the lowering of the critical temperature.
