In this work, Bi1.6Pb0.4Sr2Ca2Cu3Oy thin films have been fabricated by pulsed laser deposition (PLD) onto substrate of MgO single crystal. Bi(Pb)SrCaCuO thin films with different deposition times were annealed at different annealing temperature. Zero resistances of thin films were registered in the range of 30−68 K after annealing treatment and strongly dependent on the annealed temperature. From scanning electron microscope (SEM) pictures, it is observed that annealing temperature have a pronounced influence on the particle structure. Energy dispersive X-ray (EDX) analyses show the presence of elements Bi, Pb, Sr, Ca and Cu and suggest a strong loss of the Pb component in all annealed thin films. All measurements indicate that the films were mainly dominated by the 2212 phase and results showed that superconducting transitions are affected by the annealing treatment temperature and it can be an effective method to change the oxygen in the Bi(Pb)SrCaCuO system and vary its superconducting properties.
