Electric Polarization of a Double-Layer Exchange-Coupled Ferromagnetic Film

Abstract

The electric polarization for the vortex distribution of magnetization in a double-layer exchange-coupled ferromagnetic film of finite dimensions is studied numerically. The electric polarization of such a film is determined by its component of perpendicular magnetization. The contribution to the electrical polarization of individual layers of a sample is different and depends on the size of the film. As the transverse dimensions of the film shrink, the value of the average polarization grows. When magnetized in the perpendicular direction, the average polarization passes through a maximum.
