Non-Uniform Magnetoelectric Effect in Bilayered Ferromagnetic Structure with Antiferromagnetic Coupling at Interface

摘要

Theoretical analysis of peculiarities of electric polarization arising on magnetic non -homogeneity in bilayered structure with interlayer antiferromagnetic coupling has been performed. It has been shown that the total electric polarization can be of the positive and of the negative sign or equal to zero depending on the relation between layers parameters. Electric polarization can be governed by applied magnetic field through magnetization processes occurring in a system; in its turn the electric field affects the distribution of magnetic moments.
