Abstract
Epitaxial films of Ba1-x K x BiO3 are obtained in wide ranges of K substitution (0<xx=0.5. As-grown films on MgO and SrTiO3 substrates show superconductivity when the substrate temperature is about 500°C and x values range from 0.2 to 0.5. Optical reflection for the superconducting film has a plasma wavelength of about 700 nm.Keywords
