✦ Synopsis

The effects of growth conditions on the superconductivity of Bal_xKxBiO3 (BKBO) crystals grown electrochemically have been studied. Magnetic and resistive measurements reveal that the superconductivity of BKBO crystals depends strongly on the synthesis temperature, applied voltage and current, and synthesis time. The electron-phonon coupling parameter (2vh) estimated from critical field parameters of a single crystal (To= 30 K) suggests a phonon-mediated mechanism for superconductivity in BKBO.

Reports of the oxygen isotope effect exponent in superconducting Ba, \_,KXBi03 have ranged from 0.2 1 to 0.41; however, the data from the three separate experiments taken together suggest that the exponent may depend on the isotopic substitution fraction.
