Claim Text:
1. A magnetic junction residing on a substrate and usable in a magnetic device comprising: a free layer, the free layer being switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction, the free layer having a free layer perpendicular magnetic anisotropy energy greater than a free layer out-of-plane demagnetization energy; a nonmagnetic spacer layer; and a pinned layer, the nonmagnetic spacer layer residing between the pinned layer and the free layer, the pinned layer having a pinned layer perpendicular magnetic anisotropy energy greater than a pinned layer out-of-plane demagnetization energy, at least one of the pinned layer and the free layer including a multilayer, the multilayer including at least one bilayer, each of the at least one bilayer including a first layer and a second layer, the first layer including an alloy of a magnetic transition metal and a rare earth, the second layer including an amorphous magnetic layer, the multilayer having a nonzero multilayer perpendicular magnetic anisotropy up to a temperature of at least four hundred degrees Celsius.
