Light diffraction by stripe domain structures in magnetic crystals

Light diffraction by stripe domain structures (SDS) in magnetic crystals is analyzed theoretically. The applicability of the Fresnel‐Kirchhoff integral for description of magneto‐optical diffraction is discussed. In this connection a criterion of an optically thin layer with SDS is proposed. The effects of symmetrical and unsymmetrical domain structure realignments on the intensity and polarization parameters of the light field diffracted by a binary magnetic grating are studied. Both linear and quadratic magneto‐optical effects are taken into account to specify the diffraction spectrum. Peculiarities of phase and amplitude light modulation by a magnetic grating are revealed.
