摘要：
A method and system provide a magnetic junction usable in a magnetic device. The magnetic junction includes a first pinned layer having a first pinned layer magnetization, a first nonmagnetic spacer layer, and a free layer having an easy axis. The first nonmagnetic spacer layer is between the first pinned layer and the free layer. The magnetic junction is configured such that the free layer is switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction and such that the free layer employs precessional switching.
