Equations of Correlational Magnetodynamics for Ferromagnetic Materials

Abstract

A new system of equations for correlational magnetodynamics was developed by means of Bogoliubov hierarchy and new approximation for multiparticle distribution functions. The system consists of two equations. One is Landau–Lifshitz–Bloch like equation, and the other describes the evolution of pair correlations. Computational results show that correlational magnetodynamics model match the direct Landau–Lifshitz better than the standard Landau–Lifshitz–Bloch equation.
