The manipulation of collective states and switching processes is of paramount importance for the development of advanced computing technologies based on unconventional multifunctional materials, including multiferroics with strong spin–orbit coupling. In this article, we explore the manifestation of Dzyaloshinskii–Moriya interaction (DMI) in the reversal magnetization processes in magnetoelectric nanomagnet. We focus on the situations realized in DMI - systems that we consider interesting for practical implementations: magnetization switching with minimum energy consumption and magnetic topological states emerging during magnetization reversal processes. In magnetoelectric materials, magnetic topological states exhibit ferroelectric properties and can be classified as polar states. We show that a square nanoelement allows the formation of several polar states (single, double and quadrupole), the number of which depends on the combination of system parameters, and explore their effect on polarization that accompanies magnetization reversal processes.
