Abstract:The magneto-optical Kerr effects in magnetic multilayered structures containing double-negative metamaterials are investigated by using transfer-matrix method. The azimuth rotations and the figure of merit of the magneto-optical effects are calculated as a function of the thickness of the layers and the frequency of the incident wave. It is shown that the magneto-optical effects are not only enhanced largely for the present system in comparison with those in the magnetic multilayered structures containing general metal materials, a giant Kerr rotation near is also observed when the thickness of the sample is far less than the resonant wavelength. The physical origination for such a phenomenon is also analyzed. This means that we can obtain large magneto-optical Kerr effects at very thin magnetic film by using the double-negative metamaterials, which benefit the application in magnetic-optical recording. | |||
