Abstract:
1. A magnetic junction for use in a magnetic device comprising: a reference layer; a nonmagnetic spacer layer; and a free layer, the nonmagnetic spacer layer residing between the reference layer and the free layer, the magnetic junction being configured such that the free layer is switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction; and wherein a portion of the magnetic junction includes at least one magnetic substructure, the at least one magnetic substructure including at least one Fe layer and at least one nonmagnetic insertion layer, the at least one Fe layer sharing at least one interface with the at least one nonmagnetic insertion layer, each of the at least one nonmagnetic insertion layer consisting of at least one of W, I, Bi, Zn, Mo, Ag, Cd and In.
