Pressure Dependence of the Crystal Structure of SrCeO3 Perovskite. —
The crystal structure of the title compound (orthorhombic space group Pmcn) is characterized by Rietveld refinement of powder neutron diffraction data at four pressures
between 0 and 7.9 GPa. The compound undergoes Ce—O bond compression, rather
than octahedral tilting as the dominant compression mechanism up to about 8 GPa.
SrCeO3 behaves atypically when compared to other AIIBIVO3 perovskites in both temperature and pressure, which is attributed to the magnitude of the Ce—O bond length.
