The structural, magnetic, magnetoresistance, optical, and magnetorefractive properties depending on parameters of layers and structure obtained nanostructured films have been investigated. Laws of interrelation of the properties of obtained films were established. The magnetic nanostructured films are characterized by great values of magnetoresistance: - 15 % in magnetic field of 300 Oe for the multilayered films Fe (10nm/ [Co (1.5nm)/Cu (2nm)]x18/Co (1.5nm); - 17 % at 300 K for х = 0.19 and 35 % at 10 К for х = 0.13 in magnetic field of 50 kOe for the metal granular films (GF) (CoFe) хAg1-x; - 8 % in metal-dielectric (CoFe)x(Al2O3)1-x films. For the first time in the granular films the magnetorefractive effect (MRE) consisting on dependence of optical properties from magnetic field in infra-red (IR) range of optical spectra was observed. Close correlation between MRE and GMR effects which nature is covered in spin dependences both static, and optical conductivities in IR range has been established.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
