Abstract

PrAlO3 is shown to undergo a rhombohedral (R (3) over bar 3c) to orthorhombic (Imma) phase transition upon application of pressures of up to 9.1 GPa. The structures in both phases have been refined from high-resolution synchrotron diffraction data. The structure initially evolves toward a higher-symmetry structure as the pressure is increased before ultimately undergoing a first-order transition to a lower-symmetry orthorhombic structure. This behavior appears to be related to the change in the tilting of the AlO6 groups.
