Abstract

The atomic structure of antiphase boundaries in YBa₂Cu₃O₇ thin films has been characterized by means of high resolution transmission electron microscopy. Two kinds of antiphase boundaries were found, conservative and nonconservative. The nonconservative antiphase boundaries can be related to either intrinsic or extrinsic faults. The antiphase boundaries usually end at planar defects in the a-b plane. In addition, "223" planar faults have been observed. This type of defect includes both an extra Y and an extra O layer inserted parallel to the a-b plane at the z= 1 2 position of the YBa₂Cu₃O₇ structure.
