摘要:
A thin-film superconductor includes a substrate (1), a ferroelectric film (2), and a superconducting oxide film (3). The ferroelectric film extends on the substrate. The ferroelectric film is made of a crystal containing Bi and O. The superconducting oxide film extends on the ferroelectric film, and containing Bi, Cu, and an alkaline-earth metal element. The superconducting oxide film may contain at least two different alkaline-earth metal elements.
