ABSTRACT:
A substrate for a superconducting microwave component is composed of a pair of oxide superconductor thin films formed on opposite surfaces of a dielectric substrate, respectively. After Tl-type oxide superconducting thin films are deposited the opposite surfaces of the dielectric substrate, respectively, am annealing is performed in a thallium atmosphere.
