Hybrid nanostructures superconductor-ferromagnet for superconducting spintronics

Abstract

The work is devoted to the study of the processes of formation of multilayer nanostructures, their vacuum deposition, and the manufacture of a novel functional element of spintronics - superconducting spin valve, which is a multilayer structure consisting of ferromagnetic cobalt nanolayers separated by superconductor niobium films. Multilayer nanostructures are fabricated by magnetron sputtering on (111) silicon substrates at a temperature of 300K. The prototypes of the superconducting spin valve are prepared from multilayer nanostructures by the method of sharp focus reactive ion etching (FIB). Modeling was carried out using molecular dynamics methods.

Structure and local structural defects influence on the magnetic properties of cobalt nanofilms

“…The previously conducted studies considered the influence on the final properties of the sample of such technological parameters as the temperature of the substrate on which the magnetron sputtering of nanofilms takes place, the intensity and deposition direction. The results of computational experiments are described in published papers [37][38][39].…”
