Abstract

A switching device, comprising an anti-ferromagnet structure having an upper layer and a lower layer, the upper layer and lower layer anti-ferromagnetically coupled by an exchange coupling layer, the upper and lower layer formed of a similar material but having differing volumes, and wherein the device is configured to inject symmetrically spin-polarized currents through the upper and lower layers to achieve magnetic switching of the anti-ferromagnet structure.
