Role of exchange and magnetostatic interactions in the effect of thermal magnetization of fine-crystalline alloys of highly anisotropic magnetics

The theory of micromagnetism has been applied to a system consisting of plane-parallel layers of a monoaxial magnetic which differ by the orientation of easy magnetization axes to numerically investigate the effect of thermal magnetization which was simulated by varying the anisotropy constant. It has been revealed that the effect of thermal magnetization does not show up if the exchange interaction between the layers is disregarded. An enhancement of magnetostatic interaction, which was simulated by increasing the degree of noncomplanarity of the easy magnetization axes in the system layers results in a reduction of the effect. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 8, pp. 8–11, August, 2007.
