Abstract
A method of preparing a high Tc superconducting fiber is disclosed, which comprises drawing into fiber form a core filament of a crystalline oxide, continuously depositing on the heated core filament a high Tc superconducting thin film and then depositing a protective layer on the outer surface of the high Tc superconducting thin film.
Claims32
A process for the production of a superconducting fiber comprising drawing into fiber form a core filament comprising a crystalline oxide selected from the group consisting of MgO, SrTiO.sub.3, ZrO.sub.2, SiO.sub.2, and quartz, continuously depositing, at elevated temperature, on an outer surface of said core filament a high Tc superconducting thin film layer which is mainly a high Tc superconducting compound oxide, and depositing a protective layer on an outer surface of said high Tc superconducting thin film layer,
- said crystalline oxide having an arrangement of atoms in a lattice plane nearly matched by an arrangement of atoms in a predetermined lattice plane of a crystal of said high Tc superconducting compound oxide, mismatching of said arrangement of atoms in said lattice plane in said high Tc superconducting compound oxide and said lattice plane in said crystalline oxide of said core filament being less than 30%.
