| Abstract: | We report the 17O, 207Pb NMR and 17O–207Pb SEDOR study of superconducting BaPb1-x Bi x O3 (x 0.35) oxides. Inhomogeneous The results points to the formation of microscopically inhomogeneous distribution of the carrier density in metallic phase. The local spin susceptibility is increased around Bi cation within an area, which is delimited by its two first cation shells. |
