摘要： PURPOSE:To provide a critical current density of practical magnitude and to attain application to electron device, etc., by subjecting a thin oxide superconductor film formed on a substrate to heat treatment at relatively low temp. and then irradiating the above film with oxygen plasma. CONSTITUTION:A thin oxide superconductor film is formed on a substrate and heat-treated in an oxygen-containing atmosphere at 500-700 deg.C, by which oxygen is incorporated into the thin film to a certain extent. Subsequently, the thin film is put into a vacuum chamber and oxygen plasma is produced by means of a high-frequency electric power source, and the surface of the thin film is irradiated with the above plasma. When plasma irradiation is applied to the above thin-film surface for about 1-5hr, oxygen can be sufficiently incorporated into the thin film and crystal orientational property can be improved. Accordingly, a thin oxide superconductor film having high critical current density value can be obtained.

CONSTITUTION:An oxide superconductor layer 3 is formed on a substrate 1 through a buffer layer of such as ZrO2 including Y2O3, and a stabilization layer 4 in which excess current runs, is formed thereon. As for a material of the layer 4, conductive oxide such as BaPbO3 is used. Since oxygen generated by the layer 3 is absorbed by the stabilization layer 4, degradation of the superconducting characteristic of the layer 3 is prevented.

摘要： PURPOSE:To lower the surface resistance of the oxide high-temp. superconductor to the extent of allowing the use of a device for microwaves; etc., by bringing a strong inorg. acid-contg. gas into contact with the surface of the superconductor, and selectively etching away atomic layers exclusive of Cu. CONSTITUTION:The oxide high-temp. superconductor made of a compsn. consisting of, for example, YBa2Cu3O7-x is prepd. The inorg. strong acid (for example, sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid) - contg. gas is brought into contact with the surface of this conductor. Only the other atomic layers exclusive of the Cu-O surface are selectively etched away and the Cu-O surface is formed as the uppermost layer. The surface resistance is thus lowered and the oxide high-temp. superconductor usable for the device for millimeter waves and microwaves is obtd.

摘要： PURPOSE:To prevent an insulating layer from becoming insular due to aggregation by first forming an upper superconductor layer oriented at an a-axis at a low substrate temperature, then heat treating it at a low temperature to vary it from the a-axis orientation to a c-axis orientation. CONSTITUTION:When a high temperature oxide superconductor thin film is formed by precipitation from vapor, the fact that a factor for distinctly forming a c-axis orientation and an a-axis orientation is a temperature of a substrate 11, is utilized. That is, a superconducting thin film 14 of an a-axis orientation is formed at a lower temperature of the substrate l than that of formation of a superconducting thin film 12 of a c-axis orientation. Accordingly, the film 12 of the c-axis orientation is formed at a high temperature of the substrate 11, an insulating layer 13 is formed thereon, and then the film 14 of the a-axis orientation is formed at a lower temperature of the substrate 11. Then, for example, it is heat treated in a bromine atmosphere thereby to vary the film 14 from the a-axis orientation to the c-axis orientation. Thus, it can prevent the layer 13 from becoming insular due to its aggregation.
