Important defeats on pinning of 2D pancake vortices in highly anisotropic Bi-2212 superconducting matrix with homovalent Bi/La substitution
(Elsevier Science Sa, 2015)
This comprehensive study aims to investigate the change of the flux pinning mechanism, electrical and superconducting properties of the inorganic solid Bi-2212 materials with the La inclusions inserted in the crystal ...
Effect Y substitution on the microstructure, transport and magnetic proprieties of Bi2Sr2Ca1Cu2O8+delta superconducting ceramics
(De Gruyter Open Ltd, 2016)
s In high Tc superconductors (HTSC) the activation energy gives information about the pinning properties of a sample under applied magnetic field. Pinning of vortices determines the critical current density Jc which is of ...
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 ...
Microstructural and magneto-transport properties of Bi1.6Pb0.4Sr2Ca1-xGdxCu2O8+delta superconducting ceramics
sThis study aims to investigate the effect of Gd doping on the phase formation, microstructure, transport and magnetic properties of the Bi(Pb)-2212 system. A series of superconducting bulks with a nominal composition of ...
The effect of TlF3 substitution on the weak links behaviour and AC susceptibility of Bi1.8-xTlxPb0.35Sr2Ca2Cu3OyF3x superconductors
(Elsevier Sci Ltd, 2018)
We have studied the thallium fluoride (TlF3) doping and AC field dependence of the weak links behaviour and AC susceptibility of Bi1.8-xTlxPb0.35Sr2Ca2Cu3OyF3x superconductors with range of x = 0, 0.05, 0.10 and 0.15. The ...
Modeling of Micro-Hardness in the Au-Doped YBCO Bulk Superconductors
In this study, in order to investigate the effect of Au doping on mechanical properties of YBCO, Au-doped (from x = 1 wt% to x = 20 wt%) and pure YBa2Cu3O7-x samples were prepared by standard solid-state reaction method. ...
