Title:
METAL OXIDE MATERIAL AND SUPERCONDUCTING DEVICE USING SAME
Document Type and Number:
Japanese Patent JP3242252
Kind Code:
B2
Abstract:
PURPOSE: To provide a novel metal oxide material stable to moisture without causing structural phase transfer from the tetragonal to rhombic system related to the formation of a twin crystal structure or without necessitating the heat treatment causing structural phase transfer and to furnish a superconducting element or a superconducting compact with the metal oxide material as the structural material.
CONSTITUTION: This metal oxide material consists of essential elements of Ln, M, Ba, Ti, Cu and O (Ln is Y and ≥1 kind of element or atomic group selected from La, Pr, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu) and has a hexahedron or pyramid-type pentahedron of Cu and O and an octahedron of Ti and O which are two-dimensionally arranged in the basic structure at the same time. The superconducting element and compact consists of the metal oxide material.
