摘要:

实验研究了在不同臂宽的超导环中观察持续电压的可能性。早先发现,超导和正常状态之间的交流电流的臂切换感应直流电压振荡的磁场与对应的周期内的环的磁通量子。我们使用的系统中有大量的非对称环串联连接,以调查观察这种量子现象的超导转变附近的热波动开关环段没有外部影响和持续电流是远远小于在超导状态的可能性。

英文摘要:

A possibility to observe the persistent voltage in a superconducting ring of different widths of the arms is experimentally investigated. It was earlier found that switching of the arms between superconducting and normal states by ac current induces the dc voltage oscillation in magnetic field with a period corresponding to the flux quantum inside the ring. We use systems with a large number of asymmetric rings connected in series in order to investigate the possibility to observe this quantum phenomenon near the superconducting transition where thermal fluctuations switch ring segments without external influence and the persistent current is much smaller than in the superconducting state.
