Abstract

Magneto optical activity implemented in plasmonic nanostructures provides a new functionality in active plasmonics. To what an extent, one can benefit from this new degree of freedom is still under open discussion. In this work, with the development of a wavelength parallel characterization tool for measuring the optic and MO properties of nanostructures, we present systematic studies of the magneto-optical activity of Au/[Co/Pt]n/Au nanodisk array with various of disk size, shape and grating constant.
