Abstract
The ferroelectricity and linear magnetoelectric effect (LMEE) near the surface of magnetically ordered crystals of any symmetry have been studied. These effects are due to the change in value of magnetic moment near the surface and are described by an exchange magnetoelectric energy of the scalar form P(∂M 2/∂n) where P is the electric polarization, M is the magnetic moment, n is the normal to the surface. These effects were studied in a ferromagnetic film, ferroelectric-ferromagnetic film and in two-layered contact system of ferromagnetic and ferroelectric. It was shown that LMEE at the contact increases in proportion to the dielectric susceptibility of the ferroelectric.
