Unconventional Temperature-Dependent Critical Current in the Fe-Based Hybrid Josephson Junction with a Metallic Barrier
We use the multiband Fe-based superconductor (FeSC) Ba 0.5 K 0.5 Fe 2 As 2 and the conventional superconductor Nb to fabricate a hybrid Josephson junction where an Al layer serves as a highly transparent barrier. Detailed electrical transportations are studied including the Shapiro steps and the Fra...

and the conventional superconductor Nb to fabricate a hybrid Josephson junction where an Al layer serves as a highly transparent barrier. Detailed electrical transportations are studied including the Shapiro steps and the Fraunhofer-like pattern, which indicate strong Josephson effects. An unusual temperature-dependent critical current was observed, which cannot be well described by the conventional Ambegaokar–Baratoff relation. We utilize a model considering both multiband properties in the FeSC and the conventional superconductor/normal metal/superconductor Josephson junction theory, proving that this temperature dependence on critical current is attributed to the barrier transparency of the Josephson junction. We hope our studies can be a reference for the applications or physics research of FeSC Josephson junctions. |
