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 ...
Influence of Diffusion-Annealing Temperature on the Physico-Mechanical Properties of Au-doped Bi-2223 Superconductors
In order to investigate the influence of Au doping and diffusion-annealing temperature on the mechanical and superconducting properties of Bi-2223, Bi(1.8)Pb(0.35)Sr(1.9)Ca(2.1)Cu(3)O (y) superconductors were prepared by ...
Fabrication and Superconducting Properties of Ex-Situ Processed MgB2/Fe Monofilament Tapes without any Intermediate Annealing
We have investigated the effect of annealing time and temperature on the formation of the MgB2 phase, transition temperature (T-c), lattice parameters (a and c), full width at half maximum (FWHM) of the X-ray diffraction, ...
