Density of states and current–voltage characteristics in SIsFS junctions
Density of states and current–voltage characteristics in SIsFS junctions
We study the density of states (DOS) inside superconducting Josephson SIsFS junctions with complex interlayer consisting of a thin superconducting spacer 's' between insulator I and a ferromagnetic metal F. The consideration is focused on the local density of states in the vicinity of a tunnel barrier, and it permits …
