In this paper we present magnetooptical studies of nanostructures, including three-dimensional ones, formed by deposition metal layers on the surface of structured silicon. These objects demonstrate different magnetooptical behavior. Computer simulations demonstrated vortex domain structures appearance on the ellipsoidal surface of nanoobjects. Vortex domains with common center and multi-vortex states were observed.
In this work the superposition of effects with different diffraction origins and orders by formation of resulting magnetooptical response from the structures like magneto-photonic crystals in the regions far from plasmonic resonances were investigated for the first time. The contributions into magneto-optical response from diffraction and interferential phenomena in maxima of different orders in three-dimensional systems like magneto-photonic crystals were studied. It was demonstrated that the usage of integral response in order to analyze magneto-optical effects results in disappearance of interference phenomena. Diffraction maximum of the zero order reflects represent magnetic component of magnetooptical response. Numerical evaluations of observed effects were done.
