Abstract
Nonlinear effects in ferromagnetic systems can be studied in classical limit, but it is necessary to develop the methods for a strict quantum–classical transition, because the exchange interaction is of the purely quantum origin. This is realized by the application of coherent states (CS). Two types of states are studied: spin (generalized) CS and Glauber boson CS, combined with boson representation for spin operators. An example of anisotropic Heisenberg ferromagnet is discussed in detail.
