The excitation of propagating modes in nanostructured materials is well known to enhance the magnetooptical effects. We propose a novel iron-garnet meta-surface structure and study experimentally the multifold increase of magnetooptical effects in it due to excitation of optical surface waveguide modes. Magnetic meta-surface is fabricated as magnetophotonic crystals with 1D periodicity achieved by etching of 300-nm thick bismuth-substituted iron garnet film.
