Abstract

A space-group theoretical approach has been applied to the high T _c superconducting oxide YBa₂Cu₃O _7-δ (δ∼0.3) to explain the occurrence of coherent domain boundaries. This method quantitatively accounts for the transmission electron microscopy (TEM) observations of {110} twin boundaries in the room-temperature orthorhombic phase. The possible nature of the relaxation of these twin boundaries and the atomic arrangement at these boundaries are briefly discussed.
