Extended Data Fig. 5: Powder XRD patterns of the La5Ni3O11 crystal under various pressures.
From: Pressure induced superconductivity in hybrid Ruddlesden‒Popper La5Ni3O11 single crystals
(a) Powder XRD patterns of the La5Ni3O11 crystal under various pressures in the 2ϴ range of 12–14°, where the dashed line indicates the signal from the gasket (Re). (b) Rietveld refinement of the powder XRD pattern for La5Ni3O11 at 5.8 GPa. The collected data can be well fitted via the space group P4/mmm. The blue circles and red lines represent the observed and calculated data, respectively. The blue lines indicate the difference between the observed and calculated data. The short green and cyan vertical lines indicate the calculated diffraction peak positions of La5Ni3O11 with P4/mmm space group and Re.
