Anomalous metallic phase and reduced critical current in superconducting nanowires due to inverse proximity effect
G. M. Oliveira, G. O. Steffensen, I. Casal Iglesias +7
Superconductor-to-metal transitions (SMTs) are key probes of mesoscopic superconductivity, but their interpretation can be complicated by device geometry and measurement conditions…

Coherent subgap transport in spin-split Josephson junctions
David Caldevilla-Asenjo, Gorm Ole Steffensen, Sara Catalano +6
We report the first experimental observation of subgap transport in ferromagnetic insulator/superconductor/insulator/superconductor junctions realized in EuS/Al/AlOx/Al vertical st…
