The influence of pressure on the crystal structure of LaGaO3 has been studied using synchrotron x-ray diffraction. At atmospheric pressure LaGaO3 has an orthorhombic structure in Pnma and undergoes a first-order phase transition to a rhombohedral structure near 2.5 GPa. The transition is reversible and the orthorhombic structure is recovered upon releasing the pressure below 2 GPa.
