On the Origin of Magnetoelectric Phenomena in Iron Garnet Films

Abstract

The theoretical microscopic consideration of antisymmetric exchange in iron garnet crystals sub-jected to inhomogeneous deformation shows that the resulting inhomogeneous magnetoelectric effect causes electrically induced phenomena that are experimentally observed in domain walls of iron garnet films. In addi-tion, the gradient of epitaxial strains is sufficient for development of chiral magnetic structures in these films.
