标题： A possibility of persistent voltage observation in a system of asymmetric superconducting rings

摘要： 在不同宽度的超导环中观察持续电压的可能性被实验研究。 之前发现，通过交流电流将环臂在超导态和正常态之间切换，会在磁场中引起直流电压振荡，其周期对应于环内的通量量子。 我们使用由大量不对称环串联组成的系统，以研究在超导转变附近观察这种量子现象的可能性，此时热涨落会使环段在无外部影响的情况下切换，且持续电流远小于超导状态下的电流。 显示英文摘要

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.
