内容記述(抄録等)
In order to establish the fabrication method of high-Tc REBa2Cu3Oy (RE123) films by feasible simple system, we fabricated the RE123 films on SrTiO3 substrate by molten hydroxide method in low temperature and 1-atm air. Obtain films of RE-123 (RE = Gd, Eu, Sm) fabricated at low temperature of 525 °C show a c-axis orientation of RE123 and REBa2Cu4O8 phases. Moreover, the Nd-123 films show a bi-axial orientation of Nd123 single phase completely above 425 °C. The Tconset of Nd123 film fabricated at 525 °C denotes 67.1 K which was drastically lower compared with previous study of Nd123 single crystalline film, and Tconset of Nd123 films degrade with decreasing fabrication temperature. We can consider that the Nd/Ba substitution was caused by lowering the fabrication temperature.
