Possible scenario of the spatially separated Fermi-Bose mixture in the superconductive bismuthates Ba_{1-x}K_xBiO_3
M. Yu. Kagan, A. P. Menushenkov, K. V. Klementev +1
A new scenario for superconductivity in the bismuthates based on the concept of a spatially separated Fermi-Bose mixture is proposed. In the framework of this scenario we qualitati…

EXAFS indication of double-well potential for oxygen vibration in Ba_{1-x}K_xBiO_3
A. P. Menushenkov, K. V. Klementev
X-ray absorption spectra of oxide systems Ba_{1-x}K_xBiO_3 and BaPbO_3 above Bi- and Pb-L3 absorption edges were investigated. It was shown that oxygen ions move in double-well pot…
