The microstructural features of Bi2Sr2-zBaxCuOy (rr = 0, 0.2, 0.3, 0.5) compounds were characterized by means of electron diffraction (ED). In this system, a new kind of crystal defect was discovered, i.e., a 180° twin boundary between (001) and (001) planes. Furthermore it was also found that the positions of satellite reflection vary with the increase of Ba content x.
