Spin-tunneling magnetoresistive elements based on multilayered nanostructures

Abstract

The results of studies of characteristics of spin-tunneling magnetoresistive (STMR) elements fabricated from multilayered nanostructures using a mask technique have been considered. The parameters of magnetic annealing of STMR elements have experimentally been obtained. The results of these experiments have shown that a magnitude of the magnetoresistive effect can increase by four to five or more times. The test samples of STMR elements, which have a magnitude of the giant magnetoresistive effect up to 50% and a resistance of 30–35 kΩ, have been studied in the absence of a magnetic field.
