Single crystals of the superconductor BaPbt \_xBixO3 with nominal compositions of x=0.25, were grown by cooling from the melt using an excess of PbO. The superconducting transitions have been measured on the grown crystals as a function of oxygen annealing and sharp transitions with TΒ’on~t at 12 K h

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
## Measurements of superconducting transition temperature T, and lattice parameters of CaLaBaCugO,(CLBCO) indicate that CLBCO is a tetragonal bulk superconductor in the oxygen-content range from y= 6.7 to 7. The T, decreases monotonously with decreasing oxygen content and no superconducting transi
