Journal Article 2025 04 10 We have experimentally examined the effect of light localization and near field effect on the magneto-opticalresponse of the two-dimensional coupled micro-ring periodic structure. For this purpose, we fabricatedmain template by laser writing system and stamped it by polydimethylsiloxane-to reach the main twodimensionalmicrostructures. Thus, we coated them with a gold layer and Ni layer as plasmonic and magneticmetasurfaces, respectively. We recorded the spectral magneto-optical longitudinal Kerr effect under 200 mTand the spectrometer’s response in all visible regions under the normal condition as well as pump and probesystem by the aid of green laser as pump. The pump was done via high numerical aperture objective lens toexcite near field of plasmon in a two-dimensional structure. Our results indicate that the localized surfaceplasmon resonance, surface lattice resonance as well as electric and magnetic dipole moments enhance themagneto-optical response in two closer channels in the middle of visible region.
