title: Wide tunability of magnetoplasmonic crystals due to excitation of multiple waveguide and plasmon modes.
abstract: Magnetoplasmonic crystals (MPC) composed of a 1D gold grating on top of a magnetic garnet layer made by a combined ion-beam etching technique are studied. We demonstrate that this method allows to make high-quality MPC. It is shown that MPC with a 30-40 nm thick perforated gold layer provides an effective excitation of two surface plasmon-polariton modes and several numbers of waveguide modes in the garnet layer. An enhancement of the transversal magneto-optical effect up to the value of 10(-2) is observed for all types of resonant modes, that propagate in the magnetic layer, due to magnetic-field control over the mode excitation which is promising for future photonic devices.
