Diffusion coefficient, activation energy and the effect of Ag-doping on some physical properties of silver doped Bi1.8Pb0.4Ca2.2Sr2Cu3Ox
(Elsevier Science Bv, 2010)
The aim of the present study is to investigate the effect of diffusion-doped silver on some physical properties of Bi1.8Pb0.4Ca2.2Sr2Cu3Ox superconducting samples and to calculate the diffusion coefficient and the activation ...
The effect of Au diffusion on some physical properties of Bi1.8Pb0.35Sr1.9Ca2.1Cu3Oy superconductors
(Elsevier Science Sa, 2009)
We have investigated the effect of the gold diffusion on the crystal structure and superconducting properties of Bi-2223 superconducting samples employing X-ray diffraction (XRD), scanning electron microscopy (SEM), critical ...
