概要
- 論文の詳細を見る
High T_c Tl-(Ba, Sr)-Ca-Cu-O superconducting filaments were successfully prepared using a technique in which suspension-spun and pyrolyzed filaments were densified by pressing and sintering. A high J_c at 77 K, 0 T of 12000 A/cm^2 was attained for the filament sintered at 840℃ for 1200 s with a zero resistance state of 102 K. Although the starting powder had a high T_c phase of Tl_2Ba_2Ca_2Cu_3O_x, the structure of the filament with high J_c was a high T_c phase of Tl_1Ba_2Ca_2Cu_4O_x due to the volatility of Tl oxide from the large surface area of the filament.
