摘要：

In suit energy dispersive X-ray diffraction measurements on layered perovskite-like manganese Ca3Mn2O7 under pressure up to 35 GP were performed by using diamond anvil cell with synchrotron radiation. The results show that two phase transitions occurred in layered perovskite-like manganese Ca3Mn2O7 at about 1.3 GPa, from tetragonal to orthorhombic and then from orthorhombic to tetragonal at about 9.5 GPa, respectively.
