摘要
A method and system for providing a magnetic element are described. The magnetic element includes pinned and free layers, a nonmagnetic spacer layer between the free and pinned layers, and a stability structure. The free layer is between the spacer layer and the stability structure. The free layer has a free layer magnetization, at least one free layer easy axis, and at least one hard axis. The stability structure includes magnetic layers and is configured to decrease a first magnetic energy corresponding to the free layer magnetization being aligned with the at least one easy axis without decreasing a second magnetic energy corresponding to the free layer magnetization being aligned with the at least one hard axis. The magnetic element is configured to allow the free layer magnetization to be switched to between states when a write current is passed through the magnetic element.
