Amplification of Magnetooptical Response in the «Nanocomposite-Bismuth Telluride» Multilayer System

The presented work is devoted to the study of magneto-optical properties of «nanocompositesemiconductor » ((Co40Fe40B20)33.9(SiO2)66.1/Te3Bi2)) multilayer structures. It has been found, that the adding of Te3Bi2 spacer regardless of composite’s compound increases a magneto-optical response and the amplification of it is the biggest among the other spacers such as Si, SiC and Cu. There has also been established a good correlation between thickness dependencies of magnetooptical (MO) and magnetotransport properties. This correlation is related to the peculiarities of interface forming at the «FM-granule - semiconductor » edge and to percolation process in multilayer structures.

Tunnel Magnetoresistive Effect in Nanostructured Composite Systems

The results of the investigation of tunnel magnetoresistive effect in a large number of metal-dielectric nanocomposites obtained by the same technology and under identical conditions are presented. The composites with multi-elemental amorphous metal phase were considered. It has been shown that the large values of the tunnel magnetoresistive effect in these composites are ensured when the value of the density of electronic states on the Fermi surface is large while other conditions are being equal. The conditions for the appearance of an anomalous positive tunneling magnetoresistance are formulated based on the study of composites with a mono-elemental ferromagnetic phase from cobalt
