Description
Twin boundaries in polycrystalline YBa2Cu3O6+δ have been studied by atom-probe field-ion microscopy. Oxygen depletion at a twin boundary in a δ=0.6 material was observed. The width of the depleted region was 6 endash 7 nm. It agrees well with the width of oxygen depletion calculated from the oxygen-depleted twin boundary model by Jou and Washburn. However, a twin boundary in a δ=0.9 material did not show any oxygen depletion. This study provides direct evidence of oxygen depletion at twin boundaries in polycrystalline YBa2Cu3O6+δ ceramics. copyright 1997 The American Physical Society
