The electronic structures of have a half-metallic character due to the metallic nature of majority-spin states and semiconducting features of minority-spin states. From results of the magnetic properties, we have found that the has a total magnetic moment of and the p–d exchange coupling is ferromagnetic between V magnetic impurity and the host carriers of O atoms. The compound exhibits a wide half-metallic gap of 1.00 eV; this factor is a fundamental characteristic of half-metallic ferromagnetic materials for spintronics applications.Lire moins >
