[13a-B406-6] Various types of Cu-O double chain layer in RE-Ba-Cu-O
Keywords:superconductor, RE sytem
CuO double chain layer in RE-Ba-Cu-O has been considered as a stable layer, while recent studies suggested that this layer is flexible in terms of constituent elements and local structure including vacancies. In addition, mprovement of critical current properties can be expected by control of distribution of the local CuO double chain layer. These will be reported wih showing various experimental results.
