Abstract

Ba(Pb,Sb)O3 is the latest addition to the group of superconducting oxides. When substituting for Pb in BaPbO3, Sb behaves crystal-chemically the same as Bi. The Sommerfeld parameter γ∞N*(0) has been estimated from measurements of the lower and upper critical fields. As for CuO and BiO superconductors, the transition temperature of ≈3.5K of the SbO compound is high in comparison to superconductors with the same density of states at EF. This points to the close similarity between BiO and Sbz.sbnd;O perovskites and distinguishes them from other superconducting oxides which have no significant O2p character at EF.
