Abstract
A superconductor structure of very high performance is realized by forming a crystalline coating on a substrate of semiconductor, etc. and epitaxially depositing a crystalline superconductor film of good quality on this crystalline coating. Especially, CaF.sub.2 crystal and ZrO.sub.2 crystal of CaF.sub.2 crystal structure have latice constants which match well with the substrate such as Si, GaAs, etc. and the superconductor. The crystalline coating may be a perovskite material such as BaTiO.sub.3 when the superconductor is a perovskite material.
