Non-Centrosymmetric Sr2IrO4 Obtained Under High Pressure
Abstract
Sr2IrO4 with strong spin-orbit coupling (SOC) and Hubbard repulsion (U) hosts Mott insulating states. The similar crystal structure, magnetic and electronic properties, particularly the d-wave gap observed in Sr2IrO4 enhanced the analogies to cuprate high-$$T_c$$ superconductor, La2CuO4. The incomplete analogy was due to the lack of broken inversion symmetry phases observed in Sr2IrO4. Here, under high pressure and high temperature conditions, we report a non-centrosymmetric Sr2IrO4. The crystal structure and its noncentrosymmetric character were determined by single crystal X-ray diffraction and high-resolution scanning transmission electron microscopy (HR-STEM). The magnetic characterization confirms the Ir4+ with $$\textit{S}$$ = 1/2 at low temperature in Sr2IrO4 with magnetic ordering occurred at around 86 K, where a larger moment is observed than the ambient pressure Sr2IrO4. Moreover, the resistivity measurement shows three-dimensional Mott variable-range hopping existed in the system. Further, this non-centrosymmetric Sr2IrO4 phase appears to be a unique material to offer further understanding of high-$$T_c$$ superconductivity.
