摘要： A Josephson junction is disclosed which includes a substrate of a single crystal having a substantially flat surface, a wiring pattern of an oxide superconductor formed on the flat surface of the substrate, and an altered region formed having a width of 300 nm or less and formed in the wiring pattern to intersect the wiring pattern, the crystal orientations of the wiring pattern on both sides of the altered region being equal to each other. The Josephson junction may be prepared by a process including the steps of: (a) coating a surface of a substrate of a single crystal with a normal metal to form a protecting layer over the surface of the substrate; (b) irradiating a predetermined portion of the protecting layer with a focused ion beam so that an irradiated portion is formed in the substrate; (c) removing the protecting layer from the substrate; and (d) forming a wiring pattern of an oxide superconductor on the surface of the substrate from which the protecting layer has been removed such that the wiring pattern crosses the irradiated portion of the substrate, thereby forming an altered portion in the wiring pattern at a position above the irradiated portion.

摘要： In a superconductor mixer, a non-linear element is provided on a substrate. The non-linear element comprises at least one Josephson junction connected in series. An antenna pattern of superconductor, an intermediate frequency output pattern of superconductor, and a bias current pattern of superconductor are connected to the non-linear element. A signal high frequency wave (RF) and a local reference frequency wave (LO) are received by the antenna pattern and then absorbed in the non-linear element to obtain an intermediate frequency (IF) signal. Then, with applying a current to the series connected Josephson junction in the non-linear element from the bias current pattern, the intermediate frequency (IF) signal as a frequency signal of a difference between the signal high frequency wave (RF) and the local reference frequency wave (LO) is output to the intermediate frequency output pattern. At this time, by varying the current supplied from the bias current pattern, a phase of the output intermediate frequency (IF) signal is varied.

摘要： When a cuprate oxide LnBa.sub.2 Cu.sub.3 O.sub.7-x (Ln=Y, Pr or Sm; 0.30.ltoreq.x.ltoreq.1) single crystal is heated for growing a film epitaxially on the crystal or for smoothing a damaged surface of the single crystal, many large protrusions occur on the surface of the oxide single crystal substrate or the film. The smooth surface of the oxides becomes rugged by the protrusions. According to the present invention, however, the oxide substrate or the oxide superconductor film can be heated in an atmosphere including oxygen of a partial pressure between 50 mTorr and 200 mTorr to prevent the protrusions from originating on the surface of the heated oxides.
