- Abstract
PbO addition in sedimentation deposition prepared films was investigated by SEM, EDX, and RT measurements to determine its effect on the formation of YBCO films. YBCO films on SrTiO (STO) (100) substrates of varying amounts of PbO were partially melted at 980 C, annealed, and oxygenated in flowing oxygen atmosphere. In addition, a YBCO sample partially melted at higher temperature was also done for comparison. From the SEM, EDX, and RT analyses, it was found that the film having 8 wt% PbO produces a film with the highest superconducting transition temperature comparable to that of a YBCO sample partially melted at peritectic point. Moreover, it was observed that addition of PbO enhances matter transport between Y123 particles and lowers the processing temperature for the fabrication of YBCO films via the sedimentation deposition method.
