Title:
SUPERCONDUCTIVE MEMBER
Document Type and Number:
Japanese Patent JPH02260672
Kind Code:
A
Abstract:
PURPOSE:To enhance a critical current and its density by a method wherein an oxide superconductor oriented layer, an oxide superconductor layer, and a normal conductor layer are successively formed in lamination on a base to form a laminated unit, and a superconductive member of this design is composed of two or more laminated units. CONSTITUTION:An oxide superconductor oriented layer 2 is formed on a base 1, an oxide superconductor layer 3 is deposited thereon, and a normal conductor layer 4 which functions as the pinning center of the superconductor layer 3 is formed thereon to form a superconductive member 5. The layer 4 is formed on a metal thin film of Fe, Ni, Co, Ag, Au, Pt, Pd, Mo, Ta, W, or the like or ally thin film of them. On the other hand, a unit is formed of a three-layered laminated body of the layers 2-4 and two or more units are successively stacked up to constitute a superconductive member 11. The oxide superconductor layers 3 separated by the layers 2 and 4 serve as current paths separately.
