Title:
PRODUCTION OF OXIDE SUPERCONDUCTOR
Document Type and Number:
Japanese Patent JPH05170437
Kind Code:
A
Abstract:
PURPOSE: To produce an ACuO2 type oxide superconductor having an infinite CuO2 layered structure, especially an oxide superconductor capable of producing a thin film suitable for application to an electronic device without using a high pressure process.
CONSTITUTION: Atoms or molecules for a monoatomic layer of A1-xMxO and atoms or molecules for a monoatomic layer of CuO are alternately deposited on a substrate heated to 510-700°C by a thin film forming method in an oxidizing atmosphere to produce the objective oxide superconductor represented by a formula (A1-xMx)Cu1Oy, [where A is at least one of alkaline earth metals, M is at least one among rare earth elements, Ag and alkaline earth metals, 0<(x)<1 and (y) is the amt. of oxygen].
