测量了掺入铜的多芯Nb-Ti超导细丝的抗磁性。当温度降低时，金属丝的抗磁性突然增加两次。第一种是由于Nb-Ti细丝的普通超导转变，第二种是由于诱导超导铜“转变”到弱耦合超导态。
The diamagnetism of a fine multi-filamentary superconducting wire of Nb–Ti embedded in Cu is measured. The wire shows two abrupt increases in diamagnetism when the temperature is decreased. The first is due to the ordinary superconducting transition of Nb–Ti filaments, while the second is caused by the “transition” into a weakly-coupled superconducting state through the induced superconducting Cu.
