N2 - We thoroughly investigated all the possible (C2 29 =406) candidates of half-metallic (HM) antiferromagnet (AFM) with the structure LaSrB B′ O6, where B B′ pairs are any combination of two 3d, 4d, and 5d transition elements. Sr was also replaced by Ca or Ba whenever HM-AFM was found and similar calculation was performed in order to probe more possibilities. We have found that LaAWX O6, where A=Ca,Sr,Ba and X=Tc,Re are potential candidates of HM-AFM. Among those HM-AFM candidates, LaA WReO6 (A=Sr,Ba) are rather robust than others for the structural optimization. Including previous Wang and Guo's work in 2006 and this work, we believe that we have found all possible HM-AFM candidates for double perovskites structure LaAB B′ O6 (A=Ca,Sr,Ba and B, B′ =transition elements).
