MULTILAYER MAGNETORESISTIVE COMPOSITE NANOSTRUCTURE Russian patent published in 2011 - IPC B82B1/00 

FIELD: chemistry.

SUBSTANCE: multilayer magnetoresistive composite nanostructure consists of a layer of magnetically soft ferromagnetic material and several alternating layers of magnetic nanoclusters. The layer of magnetically soft ferromagnetic material has thickness of 3-5 nm and the layer is separated from the magnetic nanoclusters by a layer of non-magnetic dielectric with thickness of 1.5-3.0 nm, behind which lie alternating layers of magnetic nanoclusters made from ferromagnetic material with thickness of 0.8-2.0 nm and anti-ferromagnetic dielectric material with thickness of 1.5-3.0 nm.

EFFECT: design of a composite nanostructure with high tunnel magnetoresistance effect with possibility of operation at high working temperature and high reliability of the technology of making devices based on the disclosed nanostructure.
