Abstract

The superconducting transition temperature in BaBiO3-based superconductors exceeds 30 K. Magnetic measurements are analyzed to give their density of state. The uniqueness of Bi-O and Cu-O superconductors is revealed in an updated Tc-γ plot. The two classes of compounds share basic electronic properties, particularly a partially unoccupied band with significant O 2p character, which might favor a common pairing mechanism.
