Studies of the magnetorefractive effect (MRE) in multilayers, granulated films, nanocomposites, and manganites are briefly reviewed. A simple algorithm for calculation of the MRE is proposed. The possibility to enhance the MRE by means of multipath interference in 1D magnetophotonic crystals containing a nanocomposite or manganite film as a defect is theoretically analyzed. It is shown that, in magnetophotonic crystals, the MRE may reach 50-60% in the presence of reflection. These values are three orders of magnitude larger than those observed for common magnetooptic phenomena, such as the equatorial Kerr effect, and two orders of magnitude larger than the MRE in one-layer structures.
