Abstract
A process of preparing a superconducting thin oxide film includes irradiating a target containing Bi, Sr, Ca and Cu with a laser beam to prepare a thin film of superconducting Bi.sub.2 Sr.sub.2 Ca.sub.2 Cu.sub.3 O.sub.x oxide or a thin film of superconducting Bi.sub.2 Sr.sub.2 Ca.sub.1 Cu.sub.2 O.sub.y oxide on a substrate. The process is characterized in that the target containing Bi, Sr, Ca and Cu in an atomic ratio of 2:2:2:3 is positioned to face the substrate, and the laser beam is irradiated to the target in an atmosphere having an oxygen partial pressure of 0.01-1 Torr while the temperature of the substrate is maintained in a given temperature range suitable for growing the respective superconducting thin oxide films.
