Observation of the Josephson effect in Pb/(Ba,K)Fe2As2 single crystal junctions

Xiaohang Zhang, Yoon Seok Oh, Yong Liu +4

We have fabricated c-axis Josephson junctions on single crystals of (Ba,K)Fe2As2 by using Pb as the counter electrode in two geometries, planar and point contact. Junctions in both…
