Abstract

We propose a Josephson device in which 0 and π states are controlled by an electrical current. In this system, the π state appears in a superconductor/normal metal/superconductor junction due to the nonlocal spin accumulation in the normal metal which is induced by spin injection from a ferromagnetic electrode. Our proposal offers not only possibilities for the application of superconducting spin-electronic devices but also the in-depth understanding of the spin-dependent phenomena in magnetic nanostructures.
