my.unimap-498152017-11-21T01:19:20Z The effect of additives on behavior of the high temperature Lax Y1-xBa2Cu3O7-δ superconductor Ali, Alhuthari .A Faisal, Widad M. Salwan Kamal, J. Al-Ani salwan_kamal@yahoo.com High temperature superconductor X-ray diffraction Resistivity measurement Critical temperature LaxY1-xBa2Cu3O7-δ Link to publisher's homepage at http://ijneam.unimap.edu.my/ 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. 2017-09-28T07:44:08Z 2017-09-28T07:44:08Z 2017 Article International Journal of Nanoelectronics and Materials, vol.10 (1), 2017, pages 1-10 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/49815 en Universiti Malaysia Perlis (UniMAP) |
