Abstract
In the present chapter, we consider the examples of an isotropic ferromagnet and an isotropic antiferromagnet; we shall calculate their spectra of elementary excitations and their magnetizations as a function of the temperature and the external magnetic field. In the concluding part, some further applications of the method will be indicated.
