The lattice parameter of Ba 0:6 K 0:4 BiO 3 , which is a well-studied conventional superconductor, was measured by the X-ray Rietveld method between 10 K and room temperature. A very small change in the lattice parameter could be detected in the superconducting phase. The change could be attributed
We discuss the nature of the pairing mechanism and the physical properties associated with the normal as well as the superconducting state of cubic perovskites Ba 0.6 K 0.4 BiO 3 using the strong coupling theory. An interaction potential which includes the Coulomb, electron-optical phonon and electr
The resistivity of single crystals of the cubic high temperature superconductor Ba K BiO with T =30 K has been measured in the tempera-0.60.4 3 C ture range from 4.2 to 300 K. The experimental curve is well approximated in the framework of the classical electron-phonon model of resistivity by the Gr
