High-pressure X-ray diffraction of Dy2Ti2O7. Representative high-pressure XRD patterns for Dy2Ti2O7 annealed at various temperatures: (a) 1200 °C, (b) 800 °C, (c) unannealed. Miller indicies of the pyrochlore structure are shown in (a). A transformation from pyrochlore to cotunnite occurs at high pressure. Value on the right of each diffraction pattern is pressure in GPa. Black dots in (c) indicate the presence of excess Dy2O3 in DT0.
