An investigation of magnetoresistivity properties of an Y3Ba5Cu8Oy bulk superconductor
(Elsevier Science Sa, 2015)
A bulk ceramic superconducting sample was fabricated using the standard solid state reaction (SSR) method in the stoichiometric ratio of Y:Ba:Cu:O (3:5:8). The electrical and microstructural properties of the sample were ...
Effect of Ce Addition on the Magnetoresistivity, Irreversibility Field, Upper Critical Field and Activation Energies of Bi-2212 Superconducting Ceramics
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 ...
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 ...
Effect of MgB2 addition on thermal fluxon motions of two-dimensional pancake vortices in Bi-2223 superconducting ceramics
(Elsevier Science Sa, 2017)
This study reports the variations of magnetoresistivity performance and pinning ability for the bulk Bi1.8Pb0.4Sr2(MgB2)(x)Ca2.2Cu3.0Oy ceramic materials with the MgB2 addition (0 <= x <= 0.5) in the crystal structure by ...
