La-doping effect on spin-orbit coupled Sr2IrO4 probed by x-ray absorption spectroscopy
Jie Cheng, Xuanyong Sun, Shengli Liu +5
Sr2IrO4 was predicted to be an unconventional superconductor upon carrier doping since it highly resembles the high-temperature cuprates. Here, to understand carrier doping effect…
Role of valence changes and nanoscale atomic displacements in BiS2-based superconductors
Jie Cheng, Huifei Zhai, Yu Wang +3
Superconductivity within layered crystal structures has attracted sustained interest among condensed matter community, primarily due to their exotic superconducting properties. EuB…
A critical point in Sr2-xIrO4 and less distorted IrO6 octahedra induced by deep Sr-vacancies
Jie Cheng, Shengli Liu, Bin Li +3
For the Sr2-xIrO4 system, recent work pointed out the abnormal electronic and magnetic properties around the critical point. Here, to understand Sr-vacancy effect on spin-orbit cou…
Crystal structure and physical properties of the Sr-vacant spin-orbit-coupling induced Mott insulator Sr2-xIrO4
Jimei Kong, S. L. Liu, Jie Cheng +3
A series of polycrystalline samples of Sr2-xIrO4 have been synthesized by a solid-state reaction method. The crystal structure of this doped system can be explained on the basis of…
Insulator-metal transition in deep Sr-vacant spin-orbit Mott insulator Sr2IrO4
Xuanyong Sun, S. L. Liu, Haiyun Wang +3
Sr2IrO4 exhibits a novel insulating state assisted by spin-orbit interactions. A series of polycrystalline samples of Sr2-xIrO4 have been synthesized. It is found that deep Sr-vaca…
