- 論文の詳細を見る
Textured Bi_2Sr_2CaCu_2O_8/Ag composite tapes were fabricated by both doctor blade process and dip-coating process applying partial melting and subsequent slow cooling. Texturing significantly improved current transfer across the grain boundaries and increased transport J_c. At 4.2K, J_c values well above 10^5A/cm^2 were obtained up to 25T for the doctor blade processed tapes. Small coils with 50-70 turns were fabricated using the tapes prepared by the continuous dip-coating process. 0.6T and 0.36T were generated by the coils in bias field of 12T and 25T at 4.2K, respectively.
