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

The band structure calculations on the K-doped superconductor Ba K BiO were carried out, and the effect of the oxygen content on its electronic 0.6 0.4 3αβ¦ structures was studied in the present work. The results show that the variation in the oxygen content caused by the partial substitution of K fo
We measured the upper critical field Hcz on Bar \_XK,BiOs (0.35 <x-z 0.40) single crystal down to 2 Kin pulsed magnetic fields up to 35 T. Resistive transitions in the magnetic field systematically shift as the temperature decreases and thepH curves saturate for high enough magnetic field strength.
