Improvement of Granular Critical Current Density in Bi: 2212 Superconductors

A. Sedky & S. A. Amin · Asian Journal of Physical and Chemical Sciences · 2017

We report here structural and superconducting properties of Bi1.7Pb0.3Sr2Ca YxCu2Oy superconductors with various x values (x= 0.00, x = 0.15). It is found that addition of Y3+ does not influence the phase purity of Bi: 2212, while lattice parameters are affected. Furthermore, the...

Excess Conductivity and Critical Physical Parameters of Y Substituted Ca Site of Bi: 2223 High Tc Superconductors

A. Sedky, Amna Salah & S. A. Amin · Asian Journal of Physical and Chemical Sciences · 2017

We presented here the fluctuation induced excess conductivity in Bi1.7Pb0.3Sr2Ca2-xYxCu3Oy superconductors with various x values (0.00 < x < 0.50). The logarithmic plots of excess conductivity (∆σ) and reduced temperature (ε) reveal three different values of the order param...
