Current-voltage characteristics of tunnel Josephson junctions with a ferromagnetic interlayer
Current-voltage characteristics of tunnel Josephson junctions with a ferromagnetic interlayer
We present a quantitative study of the current-voltage characteristics (CVC) of diffusive superconductor/ insulator/ ferromagnet/ superconductor (SIFS) tunnel Josephson junctions. In order to obtain the CVC we calculate the density of states (DOS) in the F/S bilayer for arbitrary length of the ferromagnetic layer, using quasiclassical theory. For a ferromagnetic …
