| 摘 要： | Using a diamond anvil cell device and synchrotron radiation, the in-situ high-pressure structure of SrMnO3 has been investigated. At pressure up to 28.6 GPa, no pressure-induced phase transition is observed. The lattice parameters as a function of pressure is reported, and the relationship of the axial compression coefficients is βa>βc. The isothermal bulk modulus K298=266(4) GPa is also obtained by fitting the pressure-volume data using the Murnaghan equation of state.
