SILICON OR GERMANIUM COMPOUND SUPERCONDUCTING MATERIAL AND ITS SUPERCONDUCTOR

Title:

SILICON OR GERMANIUM COMPOUND SUPERCONDUCTING MATERIAL AND ITS SUPERCONDUCTOR

Document Type and Number:

Japanese Patent JP3699990

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a silicon or germanium compound superconducting material which is expected to be a new material for manufacturing a high performance device and to provide a superconductor containing the material.
SOLUTION: The silicon or germanium compound superconducting material is represented by the formula Ax(B1-yCy)2 (where 0.8<x<1.2; 0<y<1 A is Ca, Sr, Ba or two or more of these elements; B is Al, Ga, In or two or more of these elements; and C is Si and/or Ge), has a crystal structure comprising a honeycomb lattice comprising the atoms B and C and a hexagonal lattice of the atom A and has ≥3 K critical temperature.
