Conference paper


High-Tc superconducting Bi-Ca-Sr-Cu-0 thin films were prepared by the spin-on pyrolysis technique using a mixed solution of 2-ethγlhexanoates of constituent metals dissolved in an organic solvent. Effects of the pyrolyzing temperature were investigated, and it was found that the films prepared by pyrolyzing as-deposited organometals at 1073K showed superconductivity without further heat treatment. X-ray diffraction examinations of these films showed that the crystallographic c-axis was oriented perpendicularly to the film surface. The superconducting transition temperature of these films observed was Tc = 90K(onset) and 77K(end).
