Claim:
1. A magnetic junction residing on a substrate and usable in a magnetic device comprising: a free layer; a nonmagnetic spacer layer; and a reference layer, the nonmagnetic spacer layer residing between reference layer and the free layer, at least one of the free layer and the reference layer including at least one Heusler multilayer, each of the at least one Heusler multilayer including a plurality of Heusler layers sharing at least one interface, the plurality of Heusler layers including a plurality of Heusler alloys, having a plurality of lattice parameters and having a plurality of coefficients of thermal expansion; wherein the magnetic junction is 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.
