X-Ray Powder Diffraction Study on the Occupancy of Oxygen Atoms in the YBa 2 Cu 3 O x Compound

The crystal structure of an YBa 2 Cu 3 O x compound prepared under various quenching temperatures has been studied by X-ray powder diffraction techniques. The orthorhombic-to-tetragonal phase transition was observed with increasing quenching temperature. The change of oxygen content was determined b...

Description
Summary:The crystal structure of an YBa 2 Cu 3 O x compound prepared under various quenching temperatures has been studied by X-ray powder diffraction techniques. The orthorhombic-to-tetragonal phase transition was observed with increasing quenching temperature. The change of oxygen content was determined by gravimetric measurement. Occupancies of the oxygen atoms sandwiched between Ba-O layers were determined by profile fitting on the weak diffraction peaks of 012 and 102 reflections.
