Epitaxially grown semimetallic-Fe2VAl Heusler thin films were fabricated on single crystalline MgO (100) substrate. Crystalline structure, magnetic property, and electrical transport property of the films were investigated. Non-magnetic and bulk-like resistivity was achieved in a B2-ordred Fe2VAl film annealed at 700°C. Curret-perpendicular-to-plane (CPP-) Magnetoresistance effect in Co2MnSi/Fe2VAl/CoFe junctions was also investigated. Maximum value of MR ratio was 1.1% at room temperature, which is an evidence of spin-dependent transport through Fe 2VAl Heusler alloy.
