Abstract

Bi (Pb)-Sr-Ca-Cu-0 thin films have been fabricated using Nd-YAG Pulsed Laser Ablation on Mg0(100) substrate. The XRD patterns of the as-deposited BSCCO films show broad structures characteristic of a glassy or amorphous material. XRD spectrum exhibit epitaxial growth of BSCCO (2212) after a high temperature oxygen annealing treatment. The possible reasons for such behavior are an improvement of the films morphology, optimization of oxygen content and a change of the phase composition of the thin films. The X-ray diffraction plot shows that a film deposited for 1 h and annealed at 850°C is c-axis oriented and film annealed at 860°C consists of low Tc phase as a major phase. An increase of annealed temperature to 870°C and 880°C led to increasing the intensity of low Tc phase and the appearance of semiconducting phase. The superconducting transition temperature, Tc is highest for sample annealed at 870°C. XRD spectrum exhibit epitaxial growth of BSCCO (2212) after a high temperature oxygen annealing treatment. A high quality thin film can be obtained by not only a suitable target but also a good choice and appropriate post annealing treatment is needed.
