| Abstract: | All REVO3 phases have been prepared and characterized by x-ray powder diffraction for symmetry and unit cell parameters. LaVO3 and CeVO3 have tetragonal variations of the perovskite structure while all remaining REVO3 phases are orthorhombic and isostructural with GdFeO3. The variation of cell parameters with RE3+ ionic radius shows a steady contraction with decreasing radius for ao, co and V while bo goes through a maximum. |
