Electric field control of micromagnetic structure

The problem of electric field influence on micromagnetic structure in magnetoelectric materials is considered. The numerical simulation of electric charge density in micromagnetic structures taking into account inhomogenous magnetoelectric interaction is carried out. It is shown that in magnetoelectrics the vertical Bloch lines should carry electric dipole moment that provides the possibility of electric. field control of micromagnetic structure. Another aspect of magnetoelectricity of micromagnetic structures is spin cycloid transformation in electric field. (C) 2006 Elsevier B. V. All rights reserved.
