Abstract
A magnetic junction and method for providing the magnetic junction are described. The magnetic junction resides on a substrate and is usable in a magnetic device. The magnetic junction includes a pinned layer, a nonmagnetic spacer layer, a free layer, an oxide layer and at least one oxygen blocking layer. The free layer is switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction. The nonmagnetic spacer layer is between the pinned layer and the free layer. The oxide layer is adjacent to the free layer. The free layer is between the nonmagnetic spacer layer and the oxide layer. The oxygen blocking layer(s) has a position selected from adjacent to the oxide layer and adjacent to the pinned layer. In some aspects, the magnetic junction may also include an oxygen adsorber layer and/or a tuning layer.
