Role of diffusion-annealing time on the mechanical properties of bulk Bi-2223 superconductors diffusion-doped with Au
(Iop Publishing Ltd, 2007)
In order to investigate the role of Au doping and diffusion-annealing duration on the mechanical properties of Bi - Pb - Sr - Ca - Cu - O, Bi1.8Pb0.35Sr1.9Ca2.1Cu3Oy superconductors were prepared by standard solid- state ...
Transport, microstructure and mechanical properties of Au diffusion-doped Bi-2223 superconductors
(Elsevier Science Sa, 2008)
We have investigated the effect of the Au-diffusion on the mechanical and transport properties of the (Bi,Pb)(2)Sr(2)Ca(2)Cu(3)Oy (Bi-2223) superconducting samples with different annealing times of 10, 20 and 50 It. The ...
Substitution of Sm at Ca site in Bi1.6Pb0.4Sr2Ca2-xSmxCu3Oy superconductors
We have investigated the effect of the partial substitution of Ca by Sm in the Bi-2223 superconducting samples prepared by standard solid-state reaction method. Our investigations consisted of DC electrical resistivity, ...
Magnetic properties of Sm-doped Bi-2223 superconductor studied by low field local Hall generator ac susceptibility
We studied the grain boundary properties of Sm doped Bi(Pb)SrCaCuO using the Hall generator ac susceptibility (chi = chi' + i chi"). Hall generator is a convenient tool to investigate the shielding effect of superconductors ...
