Magnetic Screening

The highly disordered thin films of niobium nitride and features of the manifestation of the proximity effect in the NbN (S) –Aluminium (N) bilayers with a high ratio of their specific resistances NbN / Al >> 1were investigated. It was shown that the magnetic screening and critical current Ic of such SN structures significantly increase compared with the S layer. The observed effect is associated with the appearance of induced superconductivity in the N layer due to the proximity effect. The Josephson effect was demonstrated in the variable thickness bridges NbN / Al - NbN - NbN / Al made from such SN bilayers.

Thin films of topological insulator (TI) Bi2Se3 were grown onto the surfaces of FeSe2 layers of different thicknesses on Si (100) substrates by magnetron sputtering, forming bilayer films with smooth surface. Magnetic and transport measurements indicate ferromagnetism in these bilayer samples. Large coercive fields at low-temperatures and a room-temperature magnetic order were observed. Moreover, nonsaturated high-filed linear magnetoresistance (MR) and weak anti-localization effect were found in these bilayer thin films. These results indicate that the bilayer samples could have both strong spin–orbit coupling and ferromagnetic proximity effect, which are the desired features.
