On the Effect of Carbon Nano-Tubes Addition on Structure and Superconducting Properties of Bi(Pb)-2223 Phase
In this work, a series of ceramic samples of Bi1.6Pb0.4Sr2Ca2Cu3O (y) (Bi(Pb)-2223) added with different amounts (0, 0.2 and 0.4 wt%) of carbon nano-tubes (CNT) are prepared from commercial powders and characterized. The ...
Effect of Yttrium Doping on Magneto-transport Properties of Bi(Pb)-2212 Superconductors
An analysis of the temperature dependence of resistivity results under magnetic fields (0-7 T) is presented for yttrium doped Bi1.6Pb0.4Sr2Ca1-x Y (x) Cu2O8+delta and Bi1.6Pb0.4Sr2-x Y (x) CaCu2O8+delta (x=0 and 0.075) ...
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 ...
