Abstract :
A novel approach for the classical description of the dynamics of magnetic systems in the presence of thermal agitation is proposed. The closed nonlinear differential equation for the average magnetization is obtained. The relation between longitudinal and transversal relaxation frequencies, is obtained. The domain wall structure and propagation near the Curie temperature are investigated. A new type of critical behavior of the wall motion is explored
