Superconducting colloids, superconducting thin layers produced therefrom, and processes for producing them
The present invention relates to a superconducting colloid prepared by an exfoliating multi-layered superconductor, represented by the formula Bi2Sr2Cam-1CumO2m+4+delta (wherein, m is 1, 2 or 3 and delta is a positive number greater than 0 and less than 1) in which a mercuric halide-organic complex is intercalated, a process thereof, a superconducting thin layer prepared using the above superconducting colloid, and a process thereof.
