摘要： A magnetic device includes a pinned magnetic layer having a first fixed magnetization vector with a first fixed magnetization direction. The magnetic device also includes a free magnetic layer having a variable magnetization vector having at least a first stable state and a second stable state. The magnetic device also has a first non-magnetic layer and a reference. The first non-magnetic layer spatially separates the pinned magnetic layer and the free magnetic layer. The magnetic device also includes a second non-magnetic layer spatially separating the free magnetic layer and the reference magnetic layer. A magnetic tunnel junction, located below the pinned magnetic layer, is formed by the free magnetic layer, the second non-magnetic layer, and the reference magnetic layer. Application of a current pulse, having either positive or negative polarity and a selected amplitude and duration, through the magnetic device switches the variable magnetization vector.
