Abstract
The present invention relates to a superconducting film having a substrate and a superconductor layer formed on the substrate, in which nano grooves are formed parallel to a current flowing direction on a substrate surface on which the superconductor layer is formed and two-dimensional crystal defects are introduced in the superconductor layer on the nano grooves, and a method of manufacturing this superconducting film. A superconducting film of the invention, which is obtained at low cost and has very high Jc, is useful in applications such as cables, magnets, shields, current limiters, microwave devices, and semifinished products of these articles.
