Abstract
An orthorhombic superconductor with composition Ba2YCu3-x O7-y was investigated at the temperature range of 24°C-600°C by single crystal X-ray diffraction method. All of the `single crystals' examined showed twinning of which the law can be explained by the point symmetry, suggesting the origin of the twinning is a transition from a tetragonal phase in cooling process. Through heating experiments, it was confirmed that these crystals show reversible orthorhombic-tetragonal transition at 575°C.Keywords
