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.eninfo:eu-repo/semantics/closedAccessUltrasonic spray pyrolysis technique (USP)HTc thin filmsMagnetizationCritical current densityJ(c)Article2651869187210.1007/s10948-012-1968-42-s2.0-84961346230N/AWOS:000323906600085Q3
