Abstract
A hysteretic magnetic Josephson junction (HMJJ) device is provided that comprises a non-magnetic spacer disposed between a first ferromagnetic layer and a second ferromagnetic layer, a first ferrimagnetic layer having a first side disposed on a side of the first ferromagnetic layer opposite the non-magnetic spacer, and a second ferrimagnetic layer having a first side disposed on a side of the second ferromagnetic layer opposite the non-magnetic spacer. The first ferrimagnetic layer and the second ferrimagnetic layer are formed from a composition that provides orthogonally magnetic responses relative to the magnetic responses of the first ferromagnetic layer and the second ferromagnetic layer. The HMJJ further comprises a first superconducting material layer having a first side disposed on a second side of the first ferromagnetic layer and a second superconducting material layer having a first side disposed on a second side of the second ferromagnetic layer.
