Predicted light scattering by Josephson vortices in layered cuprates

Light scattering by Josephson vortices is theoretically predicted. An experimental set-up for the observation of the effect is proposed. The magnetic field should be parallel to the CuO_2 layers and the crystal surface. The falling light should be at grazing angles, and the Bragg scattering must be almost backscattering. The distance between the columns of the Josephson vortices must be slightly smaller than the light-wavelength. The surface should be very clean and flat in order light scattering by surface terraces and surface roughness to give the relatively small background.
