  • In situ energy dispersive X-ray diffraction measurements on layered perovskite like manganates Ca3Mn2O7 under pressure up to 35 GPa were performed by using diamond anvil cell with synchrotron radiation. The results show that two phase transitions occured in layered perovskite-like manganates Ca3Mn2O7 under pressures in the range of 0~35 GPa. The crystal structure changes from tetragonal to orthorhombic at about 1.3 GPa, and then from orthorhombic to tetragonal at about 9.5 GPa, respectively.
