Description
Superconducting thin films of the two Cu-layer phase in the Pb-doped Bi-Sr-Ca-Cu-O system have been fabricated on {100} LaAlO3 single crystals by the metalorganic deposition from ethyl hexanoate precursors. Thin films given heat treatments in air at 850--860 degree C had resistive transitions with a Tc of 86--89 K. The zero-field transport critical current densities were in the range of 2--4x105 A/cm-2 at 77 K and 106 A cm-2 at 45 K in 200--300-nm-thick films. In contrast to c-axis oriented films grown on {100} MgO, x-ray pole figures show that the films grown on {100} LaAlO3 are epitaxial, a result confirmed by electron channeling patterns
