Abstract
The effect of Pb substitution on Tl-1212 high Tc superconductor with nominal starting composition (Tl1-xPbx)Sr2CaCu2O7-δ (x = 0.1 - 0.7) has been investigated. Nano-sized PbO (10-30 nm) was used as a starting component. The samples were synthesized using the solid-state reaction technique and studied by powder X-ray diffraction method, electrical resistance measurements and scanning electron microscopy. The resistance-temperature curves showed metallic behavior for all samples. Samples with x = 0.6 showed the highest Tc onset (89 K) and Tc zero (78 K). This sample also showed the highest peak temperature for the derivative of the resistivity (ρ) versus temperature (T) curve, dρ/dT = 85 K. The X-ray diffraction patterns showed a major Tl-1212 phase with few weak diffraction lines of the Tl-1201. The deviation of electrical resistivity from linear behavior near the transition temperature was explained in terms of excess conductivity associated with Cooper pair formation. This work showed that nano-sized PbO could be used to enhance the formation of the superconducting Tl-1212 phase.
