Magneto-Optical Effects in Nanostructures with the Spatial Modulation of the Magnetization

It is proposed the novel method of the spectrally selective detection of the spin waves. It is based on the measurement of the magneto-optical effects in magnetoplasmonic nanostructure and their dependance of the magnetization modulation. It is shown that the magnitude of the magneto-optical effects depends on the spatial phase shift between the spin wave and the plasmonic grating.
