Abstract:
A magnetoresistive random-access memory (MRAM) is disclosed. The MRAM device includes a perpendicular magnetic tunnel junction device having a reference layer, a free layer, and a precessional spin current magnetic layer. A skyrmionic enhancement layer is provided adjacent to the precessional spin current magnetic layer. The skyrmionic enhancement layer helps to improve the response of the precessional spin current magnetic layer to applied spin polarized currents.

Claim (Index 1):
A magnetic device, comprising:\n a first synthetic antiferromagnetic structure in a first plane having a magnetization vector that is perpendicular to the first plane and having a fixed magnetization direction; an antiferromagnetic coupling layer in a second plane and disposed above the first synthetic antiferromagnetic structure; a second synthetic antiferromagnetic structure in a third plane and disposed over the antiferromagnetic coupling layer; a magnetic reference layer in a fourth plane and disposed over the second synthetic antiferromagnetic structure, the magnetic reference layer having a magnetization vector that is perpendicular to the fourth plane and having a fixed magnetization direction; a non-magnetic tunnel barrier layer in a fifth plane and disposed over the magnetic reference layer; a free magnetic layer disposed in a sixth plane over the non-magnetic tunnel barrier layer, the free magnetic layer having a magnetization vector that is perpendicular to the sixth plane and having a magnetization direction that can switch between a first magnetization direction to a second magnetization direction, the magnetic reference layer, the non-magnetic tunnel barrier layer and the free magnetic layer forming a magnetic tunnel junction; a precessional spin current magnetic layer disposed in a seventh plane that is physically separated from the free magnetic layer and coupled to the free magnetic layer by a filter coupling layer that may induce ferromagnetic or antiferromagnetic coupling between the free magnetic layer and the precessional spin current layer; and a skyrmionic enhancement layer disposed in an eighth plane over the precessional spin current magnetic layer and being formed from a heavy metal with large spin-orbit coupling such that the skyrmionic enhancement layer induces a Dzyaloshinskii-Moriya interaction at an interface between the precessional spin current magnetic layer and the skyrmionic enhancement layer thereby creating a non-collinear magnetic texture in the precessional spin current magnetic layer near the interface.
