A new approach for the preparation of in situ superconducting BSCCO films

The paper reports a new approach, based on low-pressure on-axis sputter deposition followed by high-pressure plasma treatment (OPT) for the preparation of in situ superconducting Bi-Sr-Ca-Cu-O (BSCCO) films with a high-Tc phase. It was observed that OPT is essential to lower the room-temperature resistance and to achieve superconduction in the films.
