Abstract

The perovskite oxide SrFeO3 has been investigated by high-pressure 57Fe Mössbauer spectroscopy and X-ray powder diffraction (XRD) up to 62 GPa and 56 GPa, respectively. Magnetic ordering occurs below 134 K at 0.1 MPa and below 210K at 15 GPa. Above 17 GPa, the magnetic ordering temperature increases markedly to above 400 K. The cubic crystal structure of SrFeO3 has been confirmed to persist up to 56 GPa by using XRD with synchrotron radiation.
