Superconducting thin films of the two Cu-layer phase in the Pb-doped Bi-Sr-Ca-Cu-O system have been fabricated on {l brace}100{r brace} LaAlO{sub 3} 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 {ital T}{sub {ital c}} of 86--89 K. The zero-field transport critical current densities were in the range of 2--4{times}10{sup 5} A/cm{sup {minus}2} at 77 K and 10{sup 6} A cm{sup {minus}2} at 45 K in 200--300-nm-thick films. In contrast to {ital c}-axis oriented films grown on {l brace}100{r brace} MgO, x-ray pole figures show that the films grown on {l brace}100{r brace} LaAlO{sub 3} are epitaxial, a result confirmed by electron channeling patterns.
