Abstract
A method and system provide a magnetic junction usable in a magnetic device. The magnetic junction includes a pinned layer, a nonmagnetic spacer layer, a free layer, and at least one damping reduction layer. The free layer has an intrinsic damping constant. The nonmagnetic spacer layer is between the pinned layer and the free layer. The at least one damping reduction layer is adjacent to at least a portion of the free layer and configured to reduce the intrinsic damping constant of 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.
