Abstract
A method of fabricating a thin-film Hg-containing oxide superconductor is disclosed, which comprises forming a thin film on a substrate, said thin film containing mercury, an alkaline earth element, and copper as main components thereof; and subjecting said substrate with the thin film to a heat treatment in an oxygen-containing atmosphere at an oxygen partial pressure of 1/500 to 1/10 atm, to convert said thin film to the thin-film superconductor.
