| Research Abstract |
For development of a new magnetic sensor based on surface plasmon phenomenon, we studied 1) clarifying an origin of magnetic response of surface plasmon, 2) achieving good response of surface plasmon magnetically, and 3) establishing a surface plasmon waveguide technique. Higher value about magnetic response of surface plasmon was obtained using a Ag-Co single layer film, which had a structure that Co particles were dispersed in Ag matrix. A generation condition of surface plasmon in Ag-Co film was easy to be controlled by its film thickness, because the Ag-Co single film contained both surface plasmon generation material, Ag, and ferromagnetic material, Co, in single layer.
