Abstract

Using density functional theory, we have investigated the structural, electronic and magnetic properties of infinitely periodic organometallic vanadium-anthracene ([V2Ant]\infinity)[V_2Ant]_\infinity) and [V4(BNAnt)2]\infinity[V_4(BNAnt)_2]_\infinity(where BNAnt is B-N analogue of anthracene) for their possible application in spintronics. From our calculations, we find that one-dimensional [V2Ant]\infinity[V_2Ant]_\infinity and [V4(BNAnt)2]\infinity[V_4(BNAnt)_2]_\infinity wires exhibit robust ferromagnetic half-metallic and metallic behavior, respectively. The finite sized V6Ant2V_6Ant_2 and V6(BNAnt)2V_6(BNAnt)_2 clusters are also found to exhibit efficient spin filter properties when coupled to graphene electrodes on either side.
