Influence of complexing agent in Tl-containing sol-gel derived precursor on critical temperature enhancement of Tl0.5Pb0.5Sr1.8Yb0.2 CaCu2O7 superconductor
Superconducting oxide ceramics of composition Tl0.5Pb0.5Sr1.8Yb0.2CaCu 2O7 was prepared by using a single-step sol-gel process using two different complexing agents (tartaric acid and citric acid). The effect of the complexing agents (0.0-11.0% (w/w %)) on superconductivity of the samples were studi...
