Abstract
We presented a numerical simulation of the processes of magnetization reversal of an exchange-coupled magnetic nanostructure, studies micromagnetic states in the system and their transformation under the influence of an external magnetic field and shows the possibility of realizing magnetic states of the Bloch point type. The influence of magnetic anisotropy constants of the “easy plane” type on the conditions of existence and structure of topological objects is studied.
