- Abstract
The perovskites Ba0.85−xLaxPr0.15(Bi0.20Pb0.80)O3−δ (0.0 ≤ x ≤ 0.07) have been synthesized by traditional solid-state method. They crystallize in P1 space group confirmed by x-ray and rotational electron diffraction data. X-ray photoelectron spectroscopy data indicate that the valences of bismuth are + 3 and + 5, while the valences of lead are + 2 and + 4 in this solid solution. They all show superconductivity. The T c zero (the highest temperature at which the sample shows zero electrical resistivity) decreases with an increase of La in the sample.
