Abstract
A layered structure which achieves both high spin polarization and low electrical resistance is provided. The layered structure includes a Heusler alloy, and graphene that is in direct contact with the surface of the Heusler alloy. Such a layered structure is fabricated by forming a thin film of the Heusler alloy over a substrate under vacuum, and growing graphene on the surface of the thin film of the Heusler alloy while maintaining the vacuum.
