In recent years, the hybrid plasmonic construction kit was expanded by magneto-optical materials, which offer magnetic tuning and non-reciprocal effects. By utilizing localized surface plasmons, the magneto-optical response of dielectric thin films can be resonantly amplified and spectrally tailored. While the experimental realization of such systems received considerable attention, so far there is no profound theoretical description that goes beyond numerical simulations. Here we present an intrisically non-reciprocal coupled oscillators model that reveals the underlying physics inside such systems and yields analytical expressions for the resonantly enhanced magneto-optical response. The predictions of the model are in good agreement with full numerical simulations of typical sample geometries as well as experiments. This includes modal dispersion, optical rotation and ellipticity.
