The temperature dependence of the crystal structure and the thermoelastic properties of SrCeO(3) have been determined from Rietveld refinement of high resolution, neutron time-of-flight powder diffraction data collected in 5 K intervals between 1273 K and 1723 K. No evidence was found for critical behaviour in the amplitudes of the modes that soften in zone boundary phase transitions in perovskite-structured phases suggesting SrCeO(3) may remain orthorhombic, space group Pbnm from 1.2 K up to… CONTINUE READING
