高温超导体中位错诱导的交流约瑟夫森效应

Dislocation induced ac Josephson effect in high-T_c superconductors

Sergei Sergeenkov, Marcel Ausloos

摘要:

本文提出了一种可能的情形,即由位错流通过机械加载但无电偏置的超导体引起交流约瑟夫森效应。在加载的YBCO晶体中(在10^7 N/m^2的外加应力下),由于位错运动而产生的特征电压估计为几个微微伏的量级(对应于10 kHz的约瑟夫森频率)。

英文摘要:

A possible scenario for an ac Josephson effect initiated by the flow of dislocations through a mechanically loaded but electrically unbiased superconductor is proposed. The characteristic voltages due to the motion of dislocations in loaded (under the applied stress of 10^7N/m^2) YBCO crystals are estimated to be of the order of a few picovolts (which corresponds to the Josephson frequency of 10 kHz).
