ABSTRACT:
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 Bi.sub.2 Sr.sub.2 CaCu.sub.2 O.sub.8+x. The nanotubes survive at treatment temperatures of up to approximately 800.degree. 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.
