Title:
SUPERCONDUCTING ELEMENT
Document Type and Number:
Japanese Patent JPH0555648
Kind Code:
A
Abstract:
PURPOSE:To improve the crystalline state of a Y1Ba2Cu3O7-x oxide superconducting thin film by a Pr1Ba2Cu3O7-y layer and to increase a substantial current capacity of a superconducting channel. CONSTITUTION:The superconducting element comprises a Pr1Ba2Cu3O7-y layer 6 formed on an MgO board 10, a superconducting channel 20 disposed near the center of a Y1Ba2Cu3O7-x oxide superconducting thin film 2 formed on the layer 6, a gate electrode 6 disposed on the channel 20 through a gate insulating layer 9, and a superconducting source electrode 3 and a superconducting drain electrode 4 formed of Y1Ba2Cu3O7-x oxide superconductor disposed at both sides of the channel 20.
