Abstract:
Resonance optical effects in ordered two-dimensional arrays of gold nanodisks embedded in an insulating magnetic film are investigated. The angle-resolved transmission spectra exhibit features related to the excitation of local surface plasmons and lattice plasmon polaritons in the gold nanoparticles and waveguide modes in the magnetic insulator layer. Resonance enhancement of the linear magneto-optical intensity effect in transmission configuration is found in the vicinity of the lattice plasmon resonance and the waveguide mode in the structures under study.
