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 ...
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, ...
The effect of the number of Ag layers on some physical properties of Bi1.8Pb0.4Ca2.2Sr2Cu3Ox
Bi1.8Pb0.4Ca2.2Sr2Cu3Ox/Ag multilayered samples with 2, 4 and 8 layers are prepared by powder in tube (PIT) method and the effect of multilayering with Ag on the superconducting and the microstructural properties of ...
