The nonlinear (at the second-harmonic frequency of the incident light) optical diffraction by a two-dimensional lattice of magnetic bubbles (cylindrical magnetic domains) is theoretically studied. Because the periods of these structures are comparable with the wavelengths of the fundamental and the second-harmonic radiation, diffraction at the second-harmonic frequency can be expected. We investigate the influence of an external magnetic field on the nonlinear magneto-optical diffraction.
