that formed as the first insulator layer, followed by gold serving as a plasmonic middle metal layer, and finally cerium-substituted iron garnet magneto-optical thin film covers all of them to reach insulator/metal/insulator structure. The magneto-optical film is formed by the pulsed laser deposition method at high vacuum. The effect of surface lattice resonance of plasmonic layer onto the overall magneto-optical activity of the structure shows two well-pronounced peaks in magneto-optical spectra due to electric and magnetic dipoles in this new magneto-plasmonic device. |
