Abstract
High-T c superconducting Bi-Pb-Sr-Ca-Cu-O films have been successfully prepared on Ag tapes by using the combination processes of screen printing, cold rolling and sintering. These highly c-axis-oriented films show a zero resistance of above 100 K. It has been found that the cold rolling process drastically improves the packing density of screen printed films as well as the critical current density J c of the tape. The J c of the film on the Ag tape at 77 K in a zero magnetic field is about 3100 A/cm2.Keywords
