Abstract
A method and composition for doped HTS tapes having directional flux pinning and critical current.
Claims15
A method of using a superconducting tape, comprising:
- providing a superconducting tape comprising a plurality of nanocolumns oriented perpendicular to the surface of the superconducting tape, the superconducting tape having a first critical current;
- applying a magnetic field parallel to a surface of the superconducting tape, wherein the magnetic field is applied at about 0.1 T at 77 K;
- and
- retaining, upon application of the magnetic field, a critical current that is at least about 90% of the first critical current.
