Abstract

Structure refinement of LaVO3 was carried out using the whole pattern fitting or Rietveld method, which is a powerful technique for extracting structural information from powder diffraction data. The crystal structure refinement was done using powder X-ray diffraction data measured on a conventional diffractometer. The structure is orthorhombic, with space group Pnma having lattice parameters a=5.5470(2) Å; b=7.8401(5) Å; c=5.5595(4) Å, V=241.778(7) Å3, Z=4, Dx=7.05 g cm-3. The structure found is isostructural with GdFeO3 in which all V sites are equivalent and V octahedra are regular. The results for the structural parameters are in a fairly good agreement with the synchrotron data published earlier.
