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...
