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.
