Optical and magnetic properties of ferromagnetical nanostructures evolving from islands to holes — •Hui Fang — Institut fuer Experimentalphysik, Freie Universitaet Berlin Arnimallee 14 D-14195 Berlin (Germany)

The optical and magneto-optic properties of nanostructured ferromagnetic films will be presented. A series of Nickel and Cobalt thin-film periodic nanostructures evolving from islands to holes were produced by the method named self-assembly sphere lithography (SSL), varying the holes diameters while keeping the lattice constant fixed. We have observed the enhancement of Kerr rotation, which is related to the surface plasmon resonances and the size and the shape of the periodic nanostructures. Further we provide the experimental demonstration of plasmonic resonances in a percolation series of periodic nanostructures even in ferromagnets.
