Abstract

We designed and realized non-concentric magnetoplasmonic-diskplasmonic-ring nanocavities. Free-space light excitation and hybridization of multipolar modes in the plasmonic nanoring with the dipolar plasmon of the magnetoplasmonic disk produce an unprecedented amplification of the magneto-optic response.
