Abstract
Solid solution Ba1−x Y x (Bi0.2Pb0.8)O3−δ with 0.00 ≤ x ≤ 0.085 has been prepared by tradition high-temperature reaction under 840 °C. X-ray and selected area electron diffraction data confirm that the samples in this solid solution crystallize in space group P1 at room temperature. X-ray photoelectron spectroscopy data indicate that the valence of bismuth in this solid solution is + 5 while the valence of lead is both + 2 and + 4. Temperature-dependent magnetic susceptibility and resistivity of the studied samples show that superconductivity can be observed for Ba1−x Y x (Bi0.2Pb0.8)O3−δ with 0.00 ≤ x ≤ 0.04. The transition temperature (\(T_{\mathrm {c}}^{\text {zero}}\)) decreases with the increase of Y in the sample, which is attributed to the increase of electronegativity of the cations.
