Outline of Final Research Achievements

I investigated the lowering of fabrication temperature and enhancing of magnetic flux pinning center for RE-Ba-Cu-O based High Temperature Superconducting film, which is expected to magnetic application. We succeeded in the fabrication of REBa2Cu4O8 (RE124) and REBa2Cu3Oy (RE123) films selectively by changing of starting materials and oxygen partial pressure via KOH flux method under 500℃. Furthermore, it found that the ultrahigh performance RE123 film is easily obtainable from post-annealing process for low-temperature fabricated RE124 phase.
