Electrically controlled hybrid superconductor–ferromagnet cell for high density cryogenic memory

Abstract: We report the fabrication and testing, at 4.2 K, of an S1IS2FS3 device, where S, F, and I denote a superconductor (Nb), a ferromagnetic material (Permalloy), and an insulator (AlOx), respectively. The F layer covers about one half of the top electrode of the S1IS2 Josephson junction and is positioned off-center. Electric current, Itr, along the S3 electrode can change the magnetization of the F layer in such a way that, for one direction of Itr, a magnetic flux penetrates the junction perpendicular to the laye… Show more

“…These elements can significantly help in the design of supercomputers, data centers, neuromorphic circuits, and quantum computing. The use of hybrid structures consisting of superconductors (S) and ferromagnets (F) is one of the modern and promising areas in the development of these devices [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”
