A single-crystal X-ray study indicates that the perovskite form of CaGeO3 is orthorhom- bic(Pbnm), and isotypic with GdFeO3, although it was previously reported as a cubic form; the cell dimensions are a : 5.26076)K,A : S.ZeSS(to), s : 7.4452(15) and v :2M.366)43 (Z: 4;...
The crystal structure of SrCeO3 perovskite, orthorhombic, space group Pmcn, has been determined from Rietveld profile refinement of neutron, time-of-flight, powder diffraction data at four pressures between 0 and 7.9GPa. The unit cell compression behaviour is anisotropic with κa=3.14(8)×103GPa...

MgSiOperovskite is shown to be stable in this P-T range and adopts an orthorhombic structure (space group Pbnm), thus ruling out any phase transition or decomposition to an assemblage of denser oxides. Structural refinements show an increase of the orthorhombic distortion with increasing pressure,...

The distortion of the orthorhombic perovskite (space group Pbnm), characterized by the tilting angle of the VO6 octahedra, progressively increases from La to Lu due to simple steric factors. Additionally, all of the perovskites show a subtle distortion of the VO6 octahedra which significantly ...
The crystal structure of the perovskite transforms reversibly from orthorhombic (Pbnm) to tetragonal (P4/mbm) to cubic (Pm3m) with change of pressure and temperature and also with K{sup +} concentration. The tilt angle of the MgF{sub 6} octahedral framework decreases continually and the ...
