5 Temperature dependence of lower critical field of YBCO Superconductor.
In: 2nd International Conference on Condensed Matter and Applied Physics (ICC), NOV 24-25, 2017, Bikaner, INDIA.
Abstract
We report the detailed study of the temperature dependence of the lower critical field (H-c1) of the YBa2Cu3O7 superconductor by magnetization measurements. The curve shows the multiband gap behavior of the sample. It is found that the sample is not a single BCS type superconductor. H-c1 is measured as the point at which the curve deviates from a Meissner-like linear M(H) curve to a nonlinear path. The H-c1 for YBCO at different temperatures from 10K to 85K has been determined by magnetization measurements M(H) with applied field parallel to the c-axis. The sample phase purity has been confirmed by Rietveld fitted X-ray diffraction data. The amplitude (1-17Oe) dependent AC susceptibility confirms the granular nature of superconducting compound. Using Bean model we calculated the temperature dependency of inter-grain critical current density and J(c)(0) is found as 699.14kAcm(-2).
