| The paper deals with the optical response from periodic lamellar magnetic structure consisting of permalloy strips on Si substrate covered by Cr protection layer. The ultrathin structure is magnetized in polar geometry and the spectral dependence of magneto-optic response is computed using rigorous coupled wave analysis. The results are compared with the data obtained from magneto-optical ellipsometry experiments. Further model computation helps to understand the basic features of the Kerr rotation spectra and reveal the possible reason of deviation between the experimental data and the model computation. |
