Probing the current-phase relation in Josephson point-contact junctions between $$\hbox {Pb}_{0.6}$$ Pb 0.6 In $$_{0.4}$$ 0.4 and $$\hbox {Ba}_{0.6}$$ Ba 0.6 K $$_{0.4}$$ 0.4 (FeAs) $$_2$$ 2 superconductors
Abstract The Josephson effect in point contacts between an “ordinary” superconductor $$\hbox {Pb}_{0.6}$$ Pb 0.6 In $$_{0.4}$$ 0.4 ( $$T_c \approx 6.6 \, {\mathrm {K}}$$ T c ≈ 6.6 K ) and single crystals of the Fe-based superconductor Ba $$_{0.6}$$ 0.6 K $$_{0.4}$$ 0.4 (FeAs) $$_2$$ 2 ( $$T_c \appro...
