Abstract

A device including a templating structure and a magnetic layer on the templating structure is described. The templating structure includes D and E. A ratio of D to E is represented by DE, with x being at least 0.4 and not more than 0.6. E includes a main constituent. The main constituent includes at least one of Al, Ga, and Ge. Further, E includes at least fifty atomic percent of the main constituent. D includes at least one constituent that includes Ir, D includes at least 50 atomic percent of the at least one constituent. The templating structure is nonmagnetic at room temperature. The magnetic layer includes at least one of a Heusler compound and an L1compound, the magnetic layer being in contact with the templating structure.
