Abstract Nano-perforated magneto-plasmonic structures
comprised of periodically arranged gold nano-islands have
been prepared by nanosphere lithography combined with
sputtering method. The coupling of magnetic materi-
als to plasmonic perforated structure provided a way to
enhance the magneto-optical rotation of the nano-perforated
magneto-plasmonic structure. This enhancement could be
seen at the first and the end of the visible spectral region
corresponding to the nanosphere-assisted localized surface
plasmon resonance modes. This concept can be useful for
the development of innovative devices for isolation, circula-
tion, and also sensor applications.
