    The magneto-optical gradient effect in anexchange-biased thin film: experimental evidencefor classical diffraction theory

  • Original language description

    The magneto-optical gradient effect decorates the boundaries of inplane domains even at perpendicular incidence of light in an optical polarization microscope. For its explanation, magneto-optical diffraction theory was previously used to derive it fromthe same gyrotropic interaction as the Kerr effect. In order to explain the symmetry of the observed contrast on bulk ferromagnetic crystals, planar as well as perpendicular subsurface gradients in the magnetization had to be assumed. This was particularly needed when the surface magnetizations in neighboring domains pointed headon and a gradient contrast appeared also in conditions of vanishing gyrotropic interaction at the surface. Such contrast should not appear in very thin films where perpendicularmagnetization gradients are not enforced by reduction of dipolar energy. Here we present the first experimental confirmation of this expectation.
