Investigation of structural and Magnetic properties of (Nb) Substituted YBCO-system
In this study, we report the synthesis and characterization of YBa2Cu3O7-δ (YBCO) high temperature superconductor prepared by solid state method and doped with Nb in different weight percentages, 0, 0.01, 0.02 and 0.05 wt%. The x-ray diffraction (XRD) analysis confirms the formation of orthorhombic...

| description | In this study, we report the synthesis and characterization of YBa2Cu3O7-δ (YBCO) high temperature superconductor prepared by solid state method and doped with Nb in different weight percentages, 0, 0.01, 0.02 and 0.05 wt%. The x-ray diffraction (XRD) analysis confirms the formation of orthorhombic phase of superconductivity for all the prepared samples. We evaluated the effects of Nb doping on the normal state resistivity (ρ), superconducting transition temperature (Tc), scanning electron microscope (SEM. The critical current densities, JC as a function of temperature have been calculated using the critical state model from the hysteresis loops up to 1T at temperature range of 10K to 60K. Magnetic flux pinning, FP of samples was calculated by using Lorentz force. XRD analysis show a shorter c axis parameter and higher orthoromthcity than the pure Y-123 and other Nb doped samples. It was also found from critical current density and magnetic flux pinning force measurement the 0.01 wt% Nb substation for Y on YBCO superconductors improve the critical current density and flux pinning force. |
