| 摘要 |
A technique for increasing the critical temperature, critical magnetic field, and maximum current density of any of a range of already known superconducting materials. The invention contemplates forming a composite structure having superconducting material in the form of fine strands embedded in a wave-guiding matrix. The superconducting current is thus restricted to essentially linear motion. The superconducting strands need not be straight, however, but could also be bent and interconnected into a network. The matrix is formed of a material having sufficiently different electrical properties from those of the superconductor so as to preserve the integrity of the superconducting current along these strands. A number of the preferred embodiments use glass as the matrix material. |
