Nanoscale Spin Valve Josephson Junction Devices



Burm Baek, William H. Rippard, Matthew R. Pufall, Samuel P. Benz, Stephen E. Russek, Horst Rogalla, Paul D. Dresselhaus


Traditionally, superconductivity and magnetism have had a mutually exclusive relationship. However, the physics of superconductor-ferromagnet hybrid structures turned out to be far from being simply destructive, which has led to the hope of a new breed of electronic devices with advantages from both worlds. In our recent publications, we experimentally show that a magnetic spin-valve embedded in a Josephson junction can change the superconductivity within the junction in a scalable way and that the spin valve states can be switched by a spintronic effect.
