Crystal Chemistry of a Nickelate Superconductor: La/Pr Distribution, Oxygen Stoichiometry, and High-Pressure Structural Evolution in La2PrNi2O7

Abstract We report a comprehensive structural characterization of La2PrNi2O7, a bilayer Ruddlesden–Popper nickelate that has been described to exhibit high-temperature superconductivity under hydrostatic pressure. Synchrotron X-ray diffraction (SXRD) data and high-resolution neut...
