Abstract
A MRAM device includes a magnetic tunnel junction containing a reference layer having a fixed magnetization direction, a free layer, and a nonmagnetic tunnel barrier layer located between the reference layer and the free layer, a negative-magnetic-anisotropy assist layer having negative magnetic anisotropy that provides an in-plane magnetization within a plane that is perpendicular to the fixed magnetization direction, and a first nonmagnetic spacer layer located between the free layer and the negative-magnetic-anisotropy assist layer.
