The theory of magnetoplasmon interaction and plasmon amplification of magneto - optical response in such structures is developed. The optical, magnetic and magneto-optical properties of fabricated plasmon and magnetoplasmon nanostructures have been studied. Prepared materials for publication and prepared interim report. A giant amplification of the magneto-optical Kerr effect (MOEK) was detected in magnetic nanogranular films coated with gold nanoparticles. The enhancement of MOEK corresponds to electronic transitions in cobalt nanogranules due to plasmon interactions between closely spaced nanoparticles of gold and cobalt. The giant enhancement of MOEK in magnetic nanogranular structures coated with gold nanoparticles may find potential application in the detection of individual molecules, in biodiagnostics and in medical therapy. Strong absorption of visible light in a thin nanostructured layer consisting of silver nanoparticles in an alumina matrix has been experimentally and theoretically demonstrated. Light absorption above 90% is observed in a wide optical range of wavelengths 240-850 nm and in a wide range of angles of incidence of light 0°-70° in thin films with a thickness of 160 nm. The general principle of enhancing light absorption in thin layers of artificial metamaterials is proposed. It has been shown that much of the light can be trapped in the nanostructured film due to the effects of light scattering by silver nanoparticles and total internal reflection. The main optical properties of these systems are studied in the framework of the theory of the effective medium using the theory of dipole polarization and macroscopic behavior, which is described by the theory of the effective environment of Maxwell-Garnett.
