Enhanced conductivity and weakened magnetism in Pb-doped Sr2IrO4

Group IV element Pb has been selected as the dopant to dope at the Sr site of Sr2IrO4.It is exciting to find that the single-phase crystal structure could be maintained with a high Pb doping level of up to x=0.3 in Sr2-xPbxIrO4.The map-ping data obtained from energy-dispersive x-ray spectroscopy analyses give solid evidence that the Pb ions are uniformly distributed in the Sr2IrO4 matrix.The incorporation of Pb leads to a moderate depression of the canted antiferromagnetic ordering state.The electrical conductivity could be greatly enhanced when the Pb doping content is higher than x=0.2.The present results give a fresh material base to explore new physics in doped Sr2IrO4 systems.
