ABSTRACT:
A magneto-optical device is disclosed that includes a non-magnetic support body and a fine particle arrangement layer on the non-magnetic support body. The fine particle arrangement layer includes multiple regularly arranged fine metal magnetic particles. In the magneto-optical device, magnetization is generated by applying an external magnetic field to the fine metal magnetic particles, and linearly polarized light is made incident on the fine metal magnetic particles, so that a magneto-optical effect is increased by the interaction between the incident light on the fine metal magnetic particles and the surface plasmon oscillation of the fine metal magnetic particles.
