From: Pressure-induced high-spin/low-spin disproportionated state in the Mott insulator FeBO3
X-ray single crystal (a) and powder (b) diffraction patterns of FeBO3 at RT at various pressures (λ = 0.2898 Å and 0.3738 Å, respectively). Note a splitting of the \((10\overline{2 })\) reflection in the SC and powder XRD pattern at 129 and 145.8 GPa, respectively, signifying lowering of the original symmetry. * marks an unidentified peak, which disappears at higher pressures.
