Resonant Enhancement of the Transverse Magneto-Optical Effect in Opal/Cobalt/Silver Plasmonic Heterostructures

Magneto-optical effects in metal–dielectric nanostructured materials based on opal films coated with a thin cobalt/silver nanolayer, whose surface has a close-packed hexagonal lattice of metal nanohemispheres and nanoholes, have been investigated. It has been demonstrated experimentally and theoreti...

Description
Summary:Magneto-optical effects in metal–dielectric nanostructured materials based on opal films coated with a thin cobalt/silver nanolayer, whose surface has a close-packed hexagonal lattice of metal nanohemispheres and nanoholes, have been investigated. It has been demonstrated experimentally and theoretically that a wide spectrum of modes of propagating surface plasmon polaritons is excited in such a system, which leads to a resonant enhancement of the magneto-optical effect in the Voigt geometry.
