Advanced Plasmonic Structures Based on Au Nanogratings on Antiferromagnets
AIP conference proceedings(2020)
Abstract
Here we investigate the impact of surface plasmon-polaritons on the optical response of the antiferromagnet films. For the exemplary system the hybrid plasmonic 1D structures based on gold nanostrip array on top of TiO2-CuMnAs bilayer are studied. It was shown that in such system the plasmonic oscillations significantly enhance the sensitivity of the optical transmittance and reflectance to the variations of the antiferromagnet permittivity, which might be induced electrically or optically.
