High pressure X-ray diffraction study of SrMnO3 perovskite

  • 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.

High pressure X-ray diffraction study of SrMnO3 perovskite

Abstract: 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.
