| description | PURPOSE:To lower the composite specific resistance at very low temperatures of a stabilizer made from high purity aluminum. CONSTITUTION:A composite superconductor 20 is formed by joining a composite material 21 and a superconducting wire 10 together using solder 15, the composite material 21 comprising high purity aluminum 11 of rectangular cross section and a covering material 12 formed on the outside of the high purity aluminum from a material with a Hall coefficient of the same sign as that of the high purity aluminum. When in use the composite superconductor is disposed with the broad surface of the high purity aluminum 11 being parallel to an external magnetic field H. Since the sign of the Hall element of the high purity aluminum is the same as that of the Hall element of the covering material at very low temperatures, the composite specific resistance of the composite material 21 can be reduced significantly by disposing the composite superconductor in this way, and as a result the specific resistance of the whole conductor can be approximated to that of the high purity aluminum. |
