概要
- 論文の詳細を見る
Superconducting thin films of the Bi-Pb-Sr-Ca-Cu-O system have been prepared on MgO substrates by dc magnetron sputtering from a single sintered target followed by post annealing, in order to examine the effect of Pb addition. The films deposited below 600℃ are always amorphous and insulating. These films crystallize by high-temperature annealing in air and become superconducting with an onset temperature of 120 K. Zero resistivity at 107 K appears when the films are deposited at 400℃ and post-annealed at 850℃ for 15 h. Although the superconducting properties of the films were quite sensitive to the temperature and duration of the high-temperature annealing step, the growth of the high-T_c phase in the films is clearly promoted by the addition of Pb.
