Ⅰ. INTRODUCTION The discovery of high temperature superconductivity in perovskite-related oxides by Bednorz and Mulet has acted as a priming to widespread the research, both fundamental and applied, in the field of high-T_c superconductors. The superconductor parameters of these materials are critically dependent on their real crystal structures. We have therefore undertaken
