The present invention relates to a superconducting colloid prepared by an exfoliating multi-layered superconductor, represented by the formula Bi2Sr2Cam-1CumO¿2m+4+δ? (wherein, m is 1, 2 or 3 and δ 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. |
