“…Moreover, a series of theoretical work on the band structures and phase diagrams of doped Sr 2 IrO 4 have predicted that possible high-temperature superconductivity could be achieved upon proper chemical doping. [13][14][15][16] Experimentally, the effects of chemical doping on the Sr 2 IrO 4 compound have been extensively investigated during the past several years. [17][18][19][20][21][22][23][24][25][26][27][28] Many intriguing physical phenomena, such as the formation of surface Fermi arcs and pseudogaps, [20] as well as the fragmented antiferromagnetic order, [22] have been observed.…”

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 up to x=0.3 in Sr2-xPbxIrO4. The mapping 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 system.
