Effect of zirconium diffusion on the microstructural and superconducting properties of YBa2Cu3O7-delta superconductors
(Elsevier Science Sa, 2012)
This study reports not only the role of zirconium (Zr) diffusion on the superconducting, physical and microstructural properties of YBa2Cu3O7-delta (Y123) bulk superconductors prepared by the conventional solid-state ...
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 influence of Gd addition on microstructure and transport properties of Bi-2223
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 by standard solid-state reaction methods. The investigation ...
Evaluation of Microstructural and Mechanical Properties of Ag-Diffused Bulk MgB2 Superconductors
Electrical, microstructural, and mechanical properties of undiffused and Ag-diffused bulk MgB2 superconductors are systematically studied using dc resistivity, scanning electron microscopy (SEM), and Vickers microhardness ...
Improvement of superconducting properties of (Bi, Pb)-2223phase by TlF3 doping
(Elsevier Science Bv, 2016)
In this work, the superconducting properties of thallium fluoride (TlF3)doped Bi1.8-xTlxPb0.35Sr2Ca2Cu3 OyF3x(x=0-0.15)compounds are presented. The X-ray diffraction analysis shows that the proportion of (Bi, Pb)-2223phase ...
