Abstract
The manifestations of the flexomagnetoelectric effect in thin ferromagnetic films with uniaxial easy-plane anisotropy and artificially created perforations in the presence of an external electric field normal to the film plane are investigated. It is shown that the influence of inhomogeneous magnetoelectric interaction in this case leads to the transformation of magnetic structures, which is necessarily accompanied by the deviation of the magnetization vector from the sample plane. For cases where the deviation angles are small, explicit expressions describing the magnetization distribution are obtained. It is proven that the impact of an electric field of certain strength can lead to changes in the topology of the ground state of the system. A simplified model is considered, explaining the features of changes in structures of this type, as well as allowing to establish conditions for their implementation.
