Transversal magneto-optical Kerr effect in two-dimensional nickel magnetoplasmonic crystals

Abstract

Resonant transversal magneto-optical Kerr effect (TKE) is experimentally studied in 2D nickel magnetoplasmonic crystal. Gradual transition between collinear and bi-directional types of surface plasmon-polariton phase matching and its influence on TKE resonances are observed by measuring and analyzing dependence of reflectance and TKE spectra on the azimuthal angle.
