Description
Based on the temperature dependent XAFS- studies of bismuthates BaPb1-xBixO3(BPBO) and Ba1-xKxBiO3(BKBO) the model of the relationship of the local crystal and the local electronic structures have been proposed. We found that it is the local structure distortions that are mostly responsible for the main macroscopic properties of these compounds. The proposed model explains the long list of contradictions observed in transport measurements, inelastic neutron and electron scattering, UPS, XPS, EXAFS and Raman spectroscopy of the BPBO-BKBO systems. The likeness of the local peculiarities of BiO6 and CuOn complexes allows us to hope that similar approach can be applied to the copper-based superconductors
