Magneto-optical properties of three-dimensional magnetophotonic crystals

Properties of three-dimensional magneto-photonic crystals based on artificial opals were studied by optical spectroscopy. We have investigated an influence of magnetic materials embedded into opal lattice on optical and magnetic properties of synthesized composites. It was shown that increase of volume fraction of magnetic material in opal lattice leads to decrease of transmissivity of synthesized composites. We measured Faraday rotation of opal-magnetite composites and found considerable changes in the Faraday rotation inside the (111) photonic bandgap.
