| description | In the present study the effect of replacement of Pb at the Ba place in the oxygen deficient BaO layer of Ba2-x PbxCa2Cu3O8+δ with (0≤x≤0.3) cuprate superconductor has been investigated. Bulk polycrystalline specimens have been prepared by the solid state reaction process. Four probes technique is used to find the Tc. The highest Tc(offset) were 88, <77, 97and 99 K for all specimens with x = 0.0, 0.1, 0.2, and 0.3 respectively.The optimum Tc(off) of ~ 99 K and Tc(onset) ~ 106.38K has been found for the composition Ba1.7 Pb0.3Ca2Cu3O8+δ. X-ray diffraction analysis showed an orthorhombic arrangement with an increase of the c-axis for the specimens substitution with Pb as compared with those of no Pb content. The change of thePb content of all specimens created a change in the volume of the unit cell which has an important effect to obtain the superconductor state. |
