The effect of cooling rates on properties of Bi1.7Pb0.35Sr1.9Ca2.1Cu3Oy superconductors produced by solid-state reaction method
(Elsevier Science Bv, 2007)
We have investigated the effect of the cooling rates in the Bi-2223 superconducting samples prepared by standard solid-state reaction method using electrical resistivity, transport critical current density, and XRD (X-ray ...
Investigation of the cooling rate in Bi(Pb)SrCaCuO high temperature superconductor by low field AC magnetic susceptibility
(Elsevier Science Bv, 2006)
Bi1.7Pb0.35Sr1.9Ca2.1CU3Ox samples prepared by the classical method were studied by the AC magnetic susceptibility (x = x' + ix") method. The annealing of the sample was concluded under different cooling rate conditions. ...

The effect of the cooling rates on oxygen content of silver sheathed Bi-2223 bulk superconducting samples was investigated performing dc electrical resistivity, transport critical current density, ac susceptibility and ...
Effect of annealing temperature on some physical properties of MgB2 by using the Hall probe ac-susceptibility method
(Elsevier Science Bv, 2009)
A commercially available powder of MgB2 is used as starting material for the examination of the influence of the annealing temperature on the properties of this intermediate-T-c superconductor. We performed scanning electron ...
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 ...
Investigation of effect of annealing temperature on mechanical properties of MgB2
(Elsevier Science Sa, 2009)
The effect of annealing temperature on the microstructure, magnetic and mechanical properties of MgB2 superconducting samples has been studied. The study consists of XRD, SEM, ac susceptibility, Vickers microhardness and ...
