  • Superconducting thin film having columnar pinning centers utilizing nano dots and method of making the same
    Publication number: 20090048113
    Abstract: A superconducting thin film is disclosed having columnar pinning centers utilizing nano dots, and comprising nano dots (3) which are formed insularly on a substrate (2) and three-dimensionally in shape and composed of a material other than a superconducting material and also other than a material of which the substrate is formed, columnar defects (4) composed of the superconducting material and grown on the nano dots (3), respectively, a lattice defect (6) formed on a said columnar defect (4), and a thin film of the superconducting material (5) formed in those areas on the substrate which are other than those where said columnar defects are formed.
