SR-PXRD patterns of LN12 under high pressures applied using acetone as a pressure-transmitting medium. (a) Diffraction patterns in the 2θ range from 35.5° to 36.7°. The dashed lines show peak positions at atmospheric pressure. (b)–(d) Diffraction patterns with fitting result of Rietveld refinement. (b) Atmospheric pressure. The inset shows the pattern in the 2θ range from 19° to 25°. Purple lines represent profiles for the R3c phase and the Pmc21 phase. (c) 15 MPa. (d) 33 MPa. Red points, blue lines, green lines and black bars represent observed, calculated and difference intensities and positions of Bragg reflections, respectively.
