Abstract

Superconducting Bi-Sr-Ca-Cu-O thin films have been prepared on (100) MgO substrates at about 600°C by coevaporation. The c-axis lattice constant of this system was controlled to the values of 24-43 Å by changing film composition. Superconducting transition temperatures of these films were affected by substrate temperature and by a post-deposition annealing at a low temperature. The highest zero resistance temperature (T_c, zero) of the as-grown Bi₂(Sr,Ca)₃Cu₂O_x film was 79 K. The best Bi₂(Sr, Ca)₄Cu₃O_x film showed an onset temperature of 105 K and T_c, zero zero of 78 K after annealing at 400°C for 1 h.
