Abstract

Systems with coupling between magnetic and plasmonic effects can bring new developments in fields of plasmonics and magnetics. In our work we fabricate and study permalloy surfaces with one-dimensional profile modulation and various modulation parameters. Using optical characterization, ferromagnetic resonance, Brillouin light scattering and numerical methods we show that such metasurfaces demonstrate in-plane magnetic anisotropy determined by the structural geometry, and support both spin-wave and surface plasmon polariton resonances determined by the modulation parameters and sample orientation. The combination of plasmonic and magnetic properties makes these structures potential candidates for applications in magnetically controlled plasmonics and optically controlled magnetics
