Abstract

Superconducting films of Bi-Sr-Ca-Cu-O on (100) SrTiO₃ and (100) MgO were fabricated using the pulsed laser deposition technique to deposit from sintered and fluoride-containing disks. Fluoride-containing films were observed to anneal more rapidly and at slightly reduced temperatures and to contain an additional phase with 24.5 Å c-axis spacing. The preferred orientation of all films is c-axis normal to the substrate. On (100) SrTiO₃, heteroepitaxial growth of the Bi₂Sr₂Ca₁Cu₂O_8+δ phase was demonstrated using transmission electron microscopy
