Abstract: | Superconducting thin films of Bi(Pb)-Sr-Ca-CuO system were prepared by depositing the film onto silver substrate by d.c. electrodeposition
technique with dimethyl sulphoxide bath in order to examine the effect of Pb addition to the BSCCO system. The films were
deposited at the potential of -0.8 V vs saturated calomel electrode (SCE) onto the silver substrate. The different preparative
parameters such as deposition potential, deposition time were studied and optimized. These films were then oxidized electro-chemically
at room temperature in an alkaline (1 N KOH) solution, and also at 600°C temperature in an oxygen atmosphere. The films showed
the superconducting behaviour, with Tc values ranging between 85 K and 96 K, respectively. |
