Electrically-controlled hybrid superconductor-ferromagnet cell for high density cryogenic memory
Ivan Nevirkovets, Oleg Mukhanov
We report the fabrication and testing, at 4.2 K, of an SISFS device, where S, F, and I denote a superconductor (Nb), a ferromagnetic material (permalloy), and an insulator (AlOx),…
Modeling the computer memory based on the ferromagnet/superconductor multilayers
Serhii E. Shafraniuk, Ivan P. Nevirkovets, Oleg A. Mukhanov
A model of superconducting computer memory exploiting the orthogonal spin transfer (OST) in the pseudospin valve (PS) that is controlled by the three-terminal Josephson superconduc…
Transduction between electrical energy and the heat in a carbon nanotube using a voltage-controlled doping
T. Gupta, I. P. Nevirkovets, V. Chandrasekhar +1
High electric conductivity ~100 MegaSiemens/m and Seebeck coefficient >200 mkV/K of carbon nanotubes (CNT) make them attractive for a variety of applications. Unfortunately, a high…
Electrical Characteristics of Superconducting-Ferromagnetic Transistors
Ivan P. Nevirkovets, Oleksandr Chernyashevskyy, Georgy V. Prokopenko +2
We report experimental results on characteristics of SFIFS junctions and multi-terminal SFIFSIS devices (where S, I, and F denote a superconductor (Nb), an insulator (AlOx), and a…
