ABSTRACT:
High-Tc superconducting ceramic oxide products and macroscopic and microscopic methods for making such high-Tc superconducting products. Completely sealed high-Tc superconducting ceramic oxide provides are made by a macroscopic process including the steps of pressing a superconducting ceramic oxide powder into a hollow body of a material inert to oxygen; heat treating the superconducting ceramic oxide powder packed body under conditions sufficient to sinter the ceramic oxide powder; and then sealing any openings of the body. Optionally, a waveform or multiple pulses of alternate magnetic filed can be applied during the heat treatment. The microscopic method of producing a high-Tc superconducting ceramic oxide product includes the steps of making a high-Tc superconducting ceramic oxide thin film; optionally sintering the deposited thin film in a magnetic filed; and removing partial oxygen content of the thin film by a scanning tunneling electron treatment machine to form a microscopic insulation layer between two high-Tc superconducting domains of the thin film.
