Micromagnetic States and Bloch Points in Multilayer Nanofilms: Influence of Anisotropy and Magnetic Field

Processes of magnetization reversal of an exchange-coupled magnetic nanostructure were numerically sumilated, micromagnetic states in the system and their transformation under the influence of an external magnetic field were studied, and the possibility of realizing magnetic states of the Bloch point type was shown. The influence of magnetic anisotropy constants of the easy plane type on the conditions of existence and structure of topological objects was investigated.
