Abstract Using three correlated band approaches, namely the conventional band approach plus on-site Coulomb repulsion U, the modified Becke-Johnson functional, and hybrid functional, we have investigated inverse-Heusler ferrimagnets Cr2Co Z ( Z =Al, Ga, In). These approaches commonly indicate that the Cr2CoAl synthesized recently is a precise compensated half-metal (CHM), whereas Cr2CoGa and Cr2CoIn are ferrimagnets with a small moment. This is also confirmed by the fixed spin moment approach… Expand
