Enhanced flux pinning in superconductors by embedding carbon nanotubes with BSCCO materials

摘要

Enhanced flux pinning in superconductors is achieved by embedding carbon nanotubes into a superconducting matrix. The carbon nanotubes simulate the structure, size and shape of heavy ion induced columnar defects in a superconductor such as Bi2Sr2CaCu2O8+x. The nanotubes survive at treatment temperatures of up to approximately 800 DEG C. both in oxygen containing and in inert atmospheres. The superconducting matrix with nanotubes is heat treated at a lower temperature than the temperature used to treat the best case pure superconductor material.
