dc.description.abstract | A series of ceramic superconductor compounds with the composition
Lax (Y) 1-x Ba2Cu3O7-δ are prepared by solid state reaction from the principle routs like La2O3, BaCO3 and CuO with high purity 99.99%. Different measurements are made to show the improvement in high phase superconductor such as resistivity measurement and the X-ray diffraction (XRD). When( x=0.20 and 0.80; x=0.40 and 0.60) an orthorhombic phase is appeared with lattice constants (a= 3.844Ao, b=3.912Ao, c=11.839Ao) and (a= 3.871Ao, b=3.881Ao, c=11.748Ao ), respectively. This emphasizes the formation of a high
temperature superconducting phase. At x=0.5 a phase is changed to a tetragonal where the superconductivity is lost. From the resistivity measurement, the highest (Tc) value is found equal to (97K) for ( x=0.20 and x=0.80) comparable with the YBCO-compound which does not normally exhibited Tc-value greater than (95K). The increase in Tc-value may be attributed to the amount of (La) and / or the oxygen content in the mixture which both influence the properties of the compound and are essential for the superconductivity phase. | en_US |
