✦ Synopsis

Fabrication and characterization of Bi2SI"2CatCU2Ox superconducting thin films, dc-magnetron sputtered from a stoichiometric oxide target on MgO and CaNdAI04 single crystals is reported. Despite a very short annealing time (5 minutes at 900 •C in air), the films are highly textured with a dominant 80-K phase. They exhibit a 5-K-wide supercondueting transition, and sustain supereurrents densities above lOS Mem 2 at temperatures below 55 K. We also demonstrate that the CaNdAI04 substrates are suitable for deposition of epitaxial Bi-based superconducting films.

Epitaxial films of the Bi,Sr,Ca,Cu,O, phase were prepared on MgO( 100) substrates in situ by RF magnetron sputtering. The as-grown film showed a T, onset of 92 K and a T, end of 82 K. The superconducting properties and the c-axis lattice constant could be varied reversibly by annealing the film in v
