Resumen
Superconducting Bi-Pb-Sr-Ca-Cu-O (BPSCCO) thin films were grown on MgO substrates by a spray pyrolysis technique, followed by a solid-state reaction. The thin films with nominal composition Bi 1.65 Pb 0.4Sr 1.2Ca 1.2Cu 2.5 (NO 3) δ were grown varying mainly the annealing temperature between 835 and 855 °C in order to observe the influence on the critical temperature T c. At 855 °C the higher T c was obtained for the 2212 phase. The thin films were then analyzed by X-ray diffraction, R-T measurements and atomic absorption spectroscopy.
