Kinetic modeling of magnetic's dynamic

Based on the Landay–Lifshitz's phenomenological equations system describes magnetic moment's dynamic on the grid and on the assumption of the multiplication the system of Fokker–Planc's kinetic equations describes evolution of the magnetic moments' on the grid distribution function has been obtained. Proposed approach seems to be especially effective in view of describing of different unbalanced processes. The system of Fokker-Planc's kinetic equations has been solved numerically by the method of the Monte-Karlo method using separation of physical processes and Runge–Kutte's scheme. Calculation results of the reversal magnetization of the noninteracting magnetic moments assembly, of the dynamic of the spontaneous polarization initiation in phase transition paramagnetic-magnetic state, of the moving domain frame in ferromagnetic are given.
