Abstract

In-doped Bi-2212 films were fabricated via sedimentation method. Scanning electron images showed Ca-rich precipitates and layered growth in indium-doped samples. X-ray diffraction analysis confirmed that the films are predominantly Bi-2212 phase, with In2O3 and Bi-2201 phase at higher doping concentration. Crystal alignment changes from highly c-axis for undoped to randomly-oriented for indium doped samples. Transport measurements reveal metallic characteristic at normal state and superconducting at Tc > 70K. Superconductivity was obtained even for highly doped sample (x = 0.7) in spite of the removal of 35% strontium, presence of Bi-2201 phase and unsubstituted indium demonstrating the stability of Bi-2212 with indium.
