Pseudosymmetry in Tetragonal Perovskite SrIrO3 Synthesized under High Pressure
{{output}}
In this study, we report a tetragonal perovskite structure of SrIrO3 (P4/mmm, a = 3.9362(9) Å, c = 7.880(3) Å) synthesized at 6 GPa and 1400 °C, employing the ambient pressure monoclinic SrIrO3 with distorted 6H structure as a precursor. The crystal structu... ...
