A Half-metallic ferrimagnet, (Mn_1-xCo_x)₂VAl is an ideal material for spintronic applications because of its high spin polarization and low saturation magnetization M_s, and theoretically becomes a fully compensated ferrimagnet at x = 0.5. However, the magneto-transport properties of the thin films have never been reported. The anomalous Hall effect (AHE) is largely affected by the electronic structure in the vicinity of the Fermi energy E_F. In this study, the relation between the AHE and the M_s in (Mn_1-xCo_x)₂VAl thin films has been systematically investigated to reveal their electronic properties.
