Abstract

A 100K superconducting Bi(Pb)-Sr-Ca-Cu-O film was formed on a MgO (100) single crystal by a spray pyrolysis method. Fifteen hours heating of the as-sprayed film at 845°C in air was enough to give the superconducting film with a Tczero higher than 100K. An X-ray diffraction pattern showed that this film mainly consisted of the high-Tc phase with the orientation of the c-axis perpendicular to the surface. Furthermore a microstructure having triple Cu-O layers without intergrowth was directly proved by high resolution TEM.
