    摘要: A metal electrode formed on an oxide superconductor for electric connection to the oxide superconductor, includes a first layer of Ag in direct contact with the oxide superconductor, and a second layer formed on the first layer. The second layer is formed of noble metal excluding Ag. The metal electrode can be formed by forming a first layer of Ag to cover a whole surface of the oxide superconductor layer, and forming a second layer of noble metal excluding Ag, to cover a whole surface of the first layer, thereby to form a double metal layer, and patterning the double metal layer so as to form a metal electrode composed of the double metal layer.

    摘要: In a process for preparing a thin film of oxide superconductor having a layered crystal structure by depositing each layer of said layered crystal structure on a substrate by Molecular Beam Epitaxy (MBE) method with introducing oxygen-containing gas which is exited by irradiation of microwave, improvement in that a film-forming operation by the MBE method is interrupted temporally after predetermined numbers of constituent layers which correspond to one unit crystal or less than one unit crystal are layered so that the deposited constituent layers are left in an activated oxygen atmosphere to effect a crystallization promotive operation, before next film-forming operation is restarted.

    摘要: A diamond synthesizing method carried out under diamond-stable superhigh pressure and temperature by employing a synthesizing vessel (10) having a plurality of synthesizing chambers (10a, 10b) divided by a partition layer (16) in the vertical direction. Solvent metals (13a, 13b) respectively placed in the upwardly arranged synthesizing chamber (10a) and the downwardly arranged synthesizing chamber (10b) are prepared so that the solvent metals are different in eutectic temperature with carbon from each other. In the respective synthesizing chambers (10a, 10b), carbon sources (12a, 12b) are placed in contact with highest-temperature portions of the respective solvent metals (13a, 13b) and seed crystals (11a, 11b) are placed in contact with lowest-temperature portions thereof. The synthesizing vessel (10) is provided with a temperature gradient in such directivity that the upper part thereof is at a higher temperature and the lower part is at a lower temperature.
