Description
The as-grown crystallized films of low T/sub c/ phase (T/sub c//similar to/80 K) in a Bi-Sr-Ca-Cu-O system were prepared by rf magnetron sputtering and were annealed in argon or oxygen atmosphere below 500 0C. Superconducting properties and the c-axis lattice constant varied according to the annealing temperature and atmosphere. These results suggest that the oxygen content in the film is varied by low-temperature annealing and that the variation of oxygen content affects the superconducting and structural properties. By cooling the sample in the chamber in 760 Torr oxygen, the as-grown film with T/sub c/ end at 74 K was obtained
