| Research Abstract |
We investigated composite structures for enhancement of magneto-optical effects assisted with surface plasmon resonance. In composite films of magnetic garnet with Au nanaoparticles formed by a repetitive formation method that changes size and number density, Faraday rotation angle was enhanced 20 times larger than that of the native garnet film at wavelength of exciting surface plasmon resonance. In composite films with Ag-Au alloy nanoparticles, enhanced Faraday rotations were obtained at the short wavelength side. A scanning near-field optical microscope was developed to obtain structural and optical information in nano-scale.
