Özet
In this study, the BiSrCaCuO (Bi-2212) films on SrTiO3 substrates were fabricated using an ultrasonic spray pyrolysis technique (USP). Structural, electrical, magnetic, and critical current density, J(c), properties of the films fabricated were investigated under different heat treatment conditions. XRD analysis showed that the films mainly consisted of the Bi-2212 phase, but the Bi-2223 phase was also detected. T-c values of the films were found between 81 K and 88 K, depending on the heat treatment conditions. J(c) values of the films were calculated using the Beans' equation. Highest J(c) value was found to be 2.93 x 10(5) A cm(-2) at 5 K and 0 T for Film C. The results obviously showed that USP method is a very effective technique for fabrication of the HTc films having high J(c) values as well as its simplicity, low cost, and easily coating.
