| Research Abstract |
Oxide superconducting wires including a rare-earth element is key technology for various energy applications in next generation. However, these wires include the rare-earth element of low Clarke number. In this study, we aimed to develop a high-Clarke-number AE-Cu-O (AE=alkaline earth) superconducting wire and investigated the fundamental study to grow the AE-Cu-O epitaxial film.
We successfully fabricated Sr-Cu-O and Ba-Cu-O epitaxial thin films by pulsed laser deposition method. However, the crystal structure of the films was orthorhombic and this means that there are many oxygen vacancies within the films. In order to introduce oxygen into the films, the films were annealed at ozone atmosphere after the deposition. As a result, the ozone-annealed films showed a tetragonal structure and we found that the oxygen was introduced into the films.
