摘要：

BaCrO4 was studied to 25 GPa in a diamond-anvil cell using both Raman spectroscopy and x-ray diffraction methods. Our results showed that BaCrO4 exhibits a phase transition near 9 GPa from both Raman and x-ray diffraction measurements. The new high-pressure phase (BaCrO4-II) is suggested as a monoclinic (P2(1)/m) structure, different from other high-pressure forms of ABO(4)-type compounds. Moreover, the high-pressure phase of BaCrO4 is found to be reversible; the low-pressure phase is recovered at similar to 8 GPa upon decompression. The pressure-volume data of BaCrO4 fitted to a third-order Birch-Murnaghan equation of state yield a bulk modulus of 53(1) GPa and a pressure derivative of 6.8(5), in agreement with the theoretical prediction. For the high-pressure phase BaCrO4-II, the bulk modulus is 117(10) GPa and the pressure derivative is 3(1).
