摘要： Improvement in a process for preparing a-axis oriented thin film of high-Tc oxide superconducting material by laser evaporation method. Before the a-axis oriented thin film of oxide superconducting material is deposited by laser evaporation method, an under-layer having an a-axis orientation of the crystal of the same oxide superconducting material is deposited on a substrate previously by sputtering.

摘要： An electrical connection between an electric conductor and an oxide superconductor is effected without the intermediary of a thin insulating layer that is formed by leaving the oxide superconductor in the atmosphere. This electrical connection is formed by removing the thin insulating layer that is formed by leaving the oxide superconductor in the atmosphere, and by electrically connecting the electric conductor and an exposed surface of the oxide superconductor.

摘要： A process for preparing a-axis oriented thin film of oxide superconducting material on a substrate by two steps. In the first step, an under-layer of an oxide superconducting material is deposited on the substrate under such a condition that the substrate is heated at a temperature which is suitable to realize an a-axis orientation of crystal of the oxide superconducting material. In the second step, an upper-layer of the same oxide superconducting material is deposited on a surface of the resulting under-layer under such a condition that the substrate is heated at a temperature which is lowered by 10.degree. to 100.degree. C. than the temperature which is used in the first step.

摘要： A tunnel junction type Josephson device includes a pair of superconductor layers formed of a compound oxide superconductor material and an insulator layer formed between the pair of superconductor layers. The insulator layer is formed of a compound oxide which is composed of the same constituent elements as those of the compound oxide superconductor material of the superconductor layers but with an atomic ratio which does not present a superconductivity characteristics. In addition, the superconductor layers and the insulator layer are continuously formed while supplying oxygen.
