The device consists of an electrically-controllable diffraction grating of magnetic domains. Any magnetic material is divided into domains within which magnetization is uniform. This configuration corresponds to an energetically favorable magnetization distribution. A ribbon magnetic domain is an elongated, straight, narrow region in which magnetization is uniform. In a thin layer of substituted garnet, BiYIG, with perpendicular surface anisotropy, the magnetization from one ribbon domain to the next is oriented alternately upwards and downwards relative to the layer surface. The width of the ribbon domains typically varies from 0.5 to 40 μm or more, and their length can reach several centimeters. Furthermore, the walls of these domains align parallel to an applied magnetic field in the plane of the layer, the width of the domains being inversely proportional to the applied field....
