We study magneto-electric (ME) coupling mechanisms in two systems, namely ferromagnetic (FM) particles dispersed in a liquid crystal (LC) and hybrid ferroelectric (FE)–FM grains. The ME effect may appear in these systems due to the rotation of nano

In this work, we demonstrate an experimental realization of a granular multiferroic composite, where the magnetic state of a nanocrystal array is modified by tuning the interparticle exchange coupling using an applied electric field. Previous theoret

We consider localized topologically nontrivial magnetic textures (skyrmions, antiskyrmions, and bimerons) in a thin magnetic film with anisotropic interfacial Dzyaloshinskii-Moriya interaction (iDMI). We use micromagnetic simulations and analytical c

We study the dependence of the Dzyaloshinskii-Moria interaction (DMI) using the $s\text{\ensuremath{-}}d$ model in the bilayer ferromagnet/heavy-metal system on the mechanical strain applied to the system. We show that DMI is sensitive to the strain

We study a hybrid system of a magnetic oxide thin film on a ferroelectric substrate. We show that magnetic and transport properties of the magnetic oxide film strongly depend on the dielectric constant and polarization of the ferroelectric substrate.

We consider phase-separated states in magnetic oxide (MO) thin films. We show that these states have a nonzero electric polarization. Moreover, the polarization is intimately related to a spatial distribution of magnetization in the film. Polarized s

We investigate the phase separated inhomogeneous charge and spin states in magnetic oxides. In particular, we study one dimensional harmonic waves and stripe structures. We show that harmonic spin charge waves are unstable and inevitably transform in

We study interlayer exchange interaction in magnetic tunnel junctions with ferroelectric barrier. We focus on the influence of image forces on the voltage dependence of the interlayer magnetic interaction (magneto-electric effect). The influence of t

We propose a model of magneto-electric effect in doped magnetic ferroelectrics. This magneto-electric effect does not involve the spin-orbit coupling and is based purely on the Coulomb interaction. We calculate magnetic phase diagram of doped magneti
