Effect of Gd addition on the activation energies of Bi-2223 superconductor
(Elsevier Science Bv, 2011)
We have investigated the effect of addition of Gd in Bi1.8Pb0.35Sr1.9Ca2.1Cu3GdxOy superconductor with x=0, 0.1, 0.2, 0.3, 0.4 and 0.5. The samples were prepared using the standard solid-state reaction method. The activation ...

This study aims to analyze the effect of Ce addition on the microstructural, superconducting and physical properties of Bi1.8Sr2.0Ce (x) Ca1.1Cu2.1O (y) ceramics with x=0, 0.001, 0.003, 0.005, 0.01, 0.03, 0.05 and 0.1 via ...
A Study on Magnetoresistivity, Activation Energy, Irreversibility and Upper Critical Field of Slightly Mn Added Bi-2223 Superconductor Ceramics
This study discusses the effect of Mn addition on the superconducting and physical properties in Bi1.8Pb0.4Sr2Mn (x) Ca2.2Cu3.0O (y) bulk superconductors with x=0,0.03,0.06,0.15,0.3, and 0.6 by means of the magnetoresistivity ...
Anisotropic nature and scaling of thermally activated dissipation mechanism in Bi-2223 superconducting thin film
(Elsevier Science Sa, 2013)
This study deals with the resistive transition of the c-axis oriented Bi-2223 thin film produced on the single crystal MgO (100) substrate using direct current (DC) magnetron reactive sputtering technique at 100 watt in ...
Investigation of the Magnetic Field Angle Dependence of Resistance and Activation Energy of DC-sputtered Bi-2223 Thin Film
(Springer Heidelberg, 2013)
This study deals with not only the effect of the applied magnetic field at different angles on critical temperature (T (c)) and activation energy (U (0)) but also the surface quality of the Bi-2223 thin film produced by ...
