Abstract
The control of transverse magneto-optical Kerr effect (TMOKE) enhancement is realized by balancing the radiative and absorption losses in one-dimensional all-nickel magnetoplasmonic crystals. The modulation of the surface shape tunes the plasmonic radiative losses and coupling of the incident light with surface plasmons. The maximal magneto-optical response corresponds to the optimal coupling implemented with the equality of radiative and absorption losses. A slight deviation from the optimal corrugation depth results in a significant reduction of the TMOKE value.
