Series arrays of superconductinghyphen;normalhyphen;superconducting junctions in the Pbhyphen;Sn lamellar eutectic alloy

摘要

Series arrays of about/100 superconductinghyphen;normalhyphen;superconducting junctions have been obtained in the oriented Pbhyphen;Sn lamellar eutectic alloy. The temperature and normal width dependences of the critical currents flowing through these Shyphen;Nhyphen;S structures have been studied and can be explained in the framework of the Bardeenhyphen;Johnson theory for systems in the clean limit.
