Patent ID: 7233039

Claim:
A magnetic element comprising: a free layer being ferromagnetic and having a free layer magnetization; a spacer layer, the spacer layer being nonmagnetic; and a pinned layer, the spacer layer residing between the pinned layer and the free layer, the pinned layer including a first ferromagnetic layer having a first magnetization, a second ferromagnetic layer having a second magnetization, a nonmagnetic spacer layer, and a spin depolarization layer, the nonmagnetic spacer layer being conductive and residing between the first ferromagnetic layer and the second ferromagnetic layer such that the first magnetization and the second magnetization are antiparallel, the spin depolarization layer being configured to depolarize at least a portion of a plurality of electrons passing through the spin depolarization layer; wherein the magnetic element is configured to allow the free layer magnetization to change direction due to spin transfer when a write current is passed through the magnetic element.
