Abstract

An analysis of the relationship between the local crystal and electronic structure of the Ba1−x KxBiO3 and BaPb1−x BixO3 perovskite systems, which was made in terms of an empirical model based on EXAFS spectroscopy studies of the above compounds, led to the conclusion that superconductivity is possible in the Ba1−x LaxPbO3 system. The Ba1−x LaxPbO3 multiphase compound synthesized at a pressure of 6.7 GPa was found to contain a superconducting phase with a critical temperature T c ⋍11 K.
