Abstract
A structure includes a tetragonal Heusler of the form MnX, in which X includes an element selected from the group consisting of Ge and Ga, with 0≦c≦3. The tetragonal Heusler is grown directly on (or more generally, over) a substrate oriented in the direction (001) and of the form YMn, wherein Y includes an element selected from the group consisting of Ir and Pt, with 0≦d≦4. The tetragonal Heusler and the substrate are in proximity with each other, thereby allowing spin-polarized current to pass from one through the other. This structure may form part of a magnetic tunnel junction magnetoresistive device, and an array of such magnetoresistive devices may together form an MRAM.
