Improvement of the critical current density in the silver sheathed Bi-Pb-Sr-Ca-Cu-O superconducting tape
Journal Article

· Appl. Phys. Lett.; (United States)
The critical current density (J/sub c/) at 77 K and in 0 T of more than 3000 A/cm/sup 2/ has been obtained in the silver sheathed Bi-Pb-Sr-Ca-Cu-O tape fabricated by the combination process of sintering and intermediate cold working. The decrease of the J/sub c/ with increasing magnetic field is much smaller in the tape prepared by this process than that prepared by sintering only. The improvement of the J/sub c/ is attributed to the improvement of the coupling between the grains of the high T/sub c/ phase. The process enhances the formation of the high T/sub c/ phase and produces a highly oriented grain structure. These are considered to be responsible for the large improvement of the coupling.
