Abstract

The present invention describes methods and systems for providing magnetic tunnel junction elements with easy-to-cone anisotropy that can be used in magnetic devices. The magnetic junction includes: a pinned layer, a non-magnetic spacer layer and a free layer. The nonmagnetic spacer layer is located between the pinned layer and the free layer. The free layer has magnetic anisotropy, at least a part of which is biaxial anisotropy. The magnetic structure is configured such that the free layer is capable of switching between a plurality of stable magnetic states when a write current is passed through the magnetic junction.
