Abstract
The influence of the Dzyaloshinskii–Moriya interaction on the formation and stability of 3D magnetic topological structures in exchange-coupled ferromagnetic films with different magnetic anisotropy has been investigated. The magnetization reversal processes in multilayer systems in the presence of a chiral magnetic layer have been analyzed. It has been shown that during the magnetization reversal, three-dimensional topological states such as Bloch points and conical skyrmions are formed, and the structure of topological defects is determined by the magnitude and sign of the Dzyaloshinskii–Moriya constant. The influence of material parameters on the magnetization reversal processes and the stabilization of micromagnetic structures has been studied.
