| Outline of Final Research Achievements |
Effect of spin-dependent scattering on the optical properties were studied by evaluating the transmittance spectra of ferromagnetic MnSb thin film and Au/ MnSb composite nanostructure, between wavelength of 200 and 1700 nm and temperature from 25 to 375℃. It was found that: (1) large shift in temperature dependent of dielectric constant at long wavelength region was observed; (2) tendency change of temperature dependent of resistivity and scattering time of conduction electron at around the Curie temperature suggested that the spin-dependent scattering is reflected in the Drude term; (3) in composite nanostructure with ferromagnetic and Au layer, the effect of spin-dependent scattering appeared in the conditions variation of Localized Surface Plasmon Resonance (LSPR).
