要約(日本語): Much attention has been paid for magneto-refractive effect with the reflection configuration (R-MRE), because this effect simply brings light intensity change according with the arrangement of magnetizations. In general, for a metallic magnetic multilayer film, a dominant factor of MRE is thought to be the spin-dependent scattering of conduction electrons and its optical properties are expressed by expanded Drude model corresponding to the magnetization state. Therefore, evaluation of scattering time and spin-dependent scattering coefficient of metallic magnetic multilayer film are of importance as material physical properties to enhance R-MRE. In this study, R-MRE of magnetic multilayer for GMR film and Ferro./Antiferro. stacked film with Surface Plasmon Resonance in Near infrared region will be introduced in the presentation.
