Аннотация
In recent years, a large number of new magnetically ordered compounds with magnetic, metamagnetic and structural phase transitions (PTs) of the 1st and 2nd orders, which accompanied with anomalies of magnetic, thermal and mechanical properties is created and studied around the world [1]. And, despite the fact that the PTs in magnetics was studied during long time both theoretically and experimentally, at the moment there is no sufficiently deep understanding of kinetics phenomena accompanying PTs. Theoretically, the growth of the new phase at PT of the 1st order is described by the kinetic equation of the Fokker-Planck [2]. The relaxation processes near PT of the 2nd order is described by the Landau-Khalatnikov equation [2]. However, the applicability of these equations for the magnetic PT has not been tested until now.
