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
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
