Abstract
While it was recently found that La2VTcO6 and La 2VCuO6 are promising candidates for half-metallic antiferromagnets (HM-AFM), the search continues for other potential candidates of HM-AFM in the double perovskites structure La2BB′O6 (B, B′=transition metal). La2VReO6 is found to be a nearly HM-AFM. Furthermore, considering correlation and spinorbital coupling (SOC) effects in transition metals, it is still nearly a HM-AFM after generalized gradient approximation with correction of on-site Coulomb interaction and SOC calculations, as reported herein.
