Peculiarities of electric polarization in bi-layered longitudinally magnetized ferrromagnetic film

Electric polarization arising in a vicinity of magnetic inhomogenety in longitudinally magnetized ferromagnetic films has been considered. A variety of polarization transformations induced by external magnetic field have been studied. It has been demonstrated that electric polarization can change continuously or with a jump-like character depending on intrinsic, mainly anisotropic properties of the layers, the direction and the value of external magnetic field.
