Abstract:
A magnetoresistive random-access memory (MRAM) is disclosed. MRAM device has a magnetic tunnel junction stack having a significantly improved performance of the free layer in the magnetic tunnel junction structure. The MRAM device utilizes a precessional spin current (PSC) magnetic layer in conjunction with a perpendicular MTJ where the in-plane magnetization direction of the PSC magnetic layer is free to rotate.

Claim (Index 10):
A magnetic device, comprising:\n a magnetic tunnel junction in a first plane comprising a free magnetic layer and a reference magnetic layer, the free magnetic layer and the reference magnetic layer separated by a non-magnetic tunneling barrier layer, the free magnetic layer having a magnetization vector that is perpendicular to the first plane and having a magnetization direction that precesses when a spin-polarized current passes there through from a first magnetization direction to a second magnetization direction; a non-magnetic spacer in a second plane disposed over the free magnetic layer; a precessional spin current means in a third plane for causing a magnetization vector with a magnetization component in the third plane to follow precession of the magnetization direction of the free magnetic layer upon application of a current to the device, wherein the magnetization component in the third plane freely rotates in any magnetic direction in the third plane, the precessional spin current means being electronically coupled through the non-magnetic spacer to the free magnetic layer, the precessional spin current means separated from the free magnetic layer by the non-magnetic spacer, wherein rotation of the magnetization component in the third plane causes spin polarization of electrons of the current passing there through to change in a manner corresponding to the magnetic vector of the precessional spin current means, thereby creating spin-polarized current, the spin-polarized current thereby causing spin transfer torque to assist switching of the magnetization vector of the free magnetic layer, the free magnetic layer storing a memory value.
