Abstract
Several decades after the discovery of superconductivity in bismuthates, the strength of their electron-phonon coupling and its evolution with doping remain puzzling. To clarify these issues, polycrystalline hole-doped Ba1−xKxBiO3 (0.1≤x≤0.6) samples were systematically synthesized and their bulk and microscopic superconducting properties were investigated by means of magnetic susceptibility and muon-spin rotation and relaxation (μSR), respectively. The phase diagram of Ba1−xKxBiO3 was reliably extended up to x=0.6, which is still fou
