Dadoenkova N. Magneto-optical effects in space-inhomogeneous magnetic media

Layered bigyrotropic magnetic media, magnetic films with magnetic domain structures, magnetic photonic crystals, ultrathin ferromagnetic multilayered structures. Development of theory of linear and nonlinear optical response from inhomogeneous magnetic media. The transfer matrix method, method of Green functions, full-potential linearized plane wave method. For the first time the total internal reflection and Goos-Hanchen effects at the boundary of two bigyrotropic magnetic media were investigated. The possibility of nonlinear magneto-optical diffraction from ordered magnetic structures was predicted. The possibility of magnetic control of the nonlinear magneto-optical diffraction is demonstrated. The effects of linear and nonlinear light reflection from magnetic and nonmagnetic films on nonmagnetic substrates is presented taking into account both misfit strains and misfit dislocations at the film and substrate interface. The investigation of the photonic band gap PBG spectra of one-dimensional magnetic photonic crystals is performed. The striped domain structures can be considered as magnetically tunable magnetic photonic crystals. The influence of the incidence angle of the electromagnetic wave and the defect layer thickness on the magneto-optical transition characteristics for the magnetic photonic crystal with defect magnetic layers is investigated. The two-defect magnetic photonic cristals can combine large values of transmission coefficient and Faraday rotation, and this fact makes them very important for the corresponding devices development. The first principle calculations of the nonlinear magneto-optical response from the ultrathin ferromagnetic structures on the base of Ni and Cu monolayers demonstrate important role of magnetic properties in nonlinear optics.
