Abstract
Abstract A superconductive structure comprising a crystalline coating (12) applied to a substrate (11) and a crystalline superconducting film (13) epitaxially deposited on said crystalline coating (12). Especially CaF₂ crystals and ZrO₂ crystals with a CaF₂ crystal structure show good lattice matching with semiconductor substrate materials such as Si, GaAs, etc., as well as with superconducting materials comprising copper oxide. The crystalline coating (12) may be made of a material having a perovskite structure, such as BaTiO₃, when the superconducting coating (13) is made of a material having a perovskite structure.
