Özet
In this paper we report our results on the effect of Zn-doping on the superconductivity properties of the compound Bi1.7Pb0.3Sr2Ca2Zn xCu3-xOy for x=0.00, 0.10, 0.15 and 0.20. The zero-resistance temperature (Tco) decreases with increasing × up to 0.20. The Tco of the pure specimen is 104.5K, while Tco for the x=0.20 sample is 90.30K. While the undoped sample has a single transition in R vs T relation, the doped samples show double transitions which become more evident for higher doped level. The volume fractions of the high-Tc phase (2223) and grain size decreased with increasing Zn content. © Tübi·tak.
