Abstract
We experimentally show the enhancement of the Faraday and transverse magneto-optical Kerr effects in the two-dimensional arrays of nanocylinders made of bismuth-substituted iron-garnet and supporting both localized and lattice modes. Simultaneous excitation of these modes makes it possible to increase the Faraday rotation by 3 times and TMOKE by an order of magnitude compared to the smooth magnetic film of the equal effective thickness. Both magneto-optical effects are enhanced in wide spectral and angular ranges making the nanocylinder array magnetic dielectric structures promising for applications with short and tightly-focused laser pulses.
