Abstract

Films of the high-temperature superconductor in the Bi-Sr-Ca-Cu-O system were deposited by pulsed laser evaporation from a ceramic disk. Films deposited onto (100) MgO show x-ray diffraction patterns characteristic of c-axis textured Bi2(Sr,Ca,Bi)3Cu2Ox phase following annealing for 10 min at 850 °C in 20% O2-80% N2. These textured films have zero resistance at 78 K and show resistance drops near 110 K. The effects of the annealing environment on the electrical and structural properties are presented.
