| dc.description.abstract | Superconducting properties of three systems with nominal stoichiometry (Bi0.7Pb0.3)SrCaCu1.5Oy (Sample A), (Bi0.5As0.2Pb0.3)SrCaCu1.5Oy(Sample B) and (Bi0.7As0.2Pb0.1)SrCaCu1.5Oy (Sample C) have been investigated using electrical resistivity, ac magnetic susceptibility and X-ray power diffraction measurements. Results show that, As is incorporated into the structure in sample B, still retaining superconducting properties but with a lower Tc of 80K. Sampel C where As is expected to replace Pb, however, does not show superconductivity and exhibit multiphase behaviour with several impuirty phases. | en_US |
