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...
