High Pressure Hot-Pressing of Y_1Ba_2Cu_3O_<7-δ> Superconductor
スポンサーリンク
概要
- 論文の詳細を見る
An almost theoretical density of Y_1Ba_2Cu_3O_<7-δ> was achieved under a high pressure of 5.4 GPa. While the pressed sample showed a semiconducting behaviour, the postannealed sample showed a superconducting transition with T_c, onset = 92K, T_c, end = 90 K. The best critical current density, J_c at 77 K was 1650 A / cm^2. The crystal structure of Y_1Ba_2Cu_3O_<7-δ> was distorted by the high pressure but recovered through annealing.
