Magneto-optical (MO) effects and optical activities (OA) look similar,
but have very different physics. We have studied that MO and OA in the
visible region are able to be modified by using localized surface
plasmons (LSPs) of metallic nanostructures. In the first part, I would
like to show modification of an MO Kerr effect of magnetic garnet films
including gold nanoparticles [1]. Second part of my talk will be devoted
to an induction of OA of a virus in the visible region using LSPs of
gold nanoparticles [2]. Finally, I would like to show a meta-interface
consisting of chiral and absorptive layers without a magnetic field
brings about a non-reciprocal optical phenomenon, which is similar to MO
effects [3].
