From: Probing the current-phase relation in Josephson point-contact junctions between \(\hbox {Pb}_{0.6}\)In\(_{0.4}\) and \(\hbox {Ba}_{0.6}\)K\(_{0.4}\)(FeAs)\(_2\) superconductors

Schemes of the point-contacts forming the four-probe electric connections for \(I-V\) measurements in a microwave field P. FeBS single-crystal plate was clamped by In on a foiled glass-fiber plastic substrate. The movable PbIn S electrode was soldered to copper wire and was pressed to the FeBS plate. A probe current I is injected into the PC and the voltage drop V across the contact is measured. The microwave signal was supplied by a cable. (a) Scheme of the PC with current injection along ab plane. (b) PC with current injection along c axis.
