Abstract:

We demonstrate theoretically and experimentally that a ferromagnetic layer as thin as a few nanometres, which is almost transparent for non-superconducting charge transport, can be used as a cut-off filter to block transport of charge-carrier superconducting correlations. This property may be exploited in some applications, as is exemplified by the case of double-barrier S1IS2FIS3 multi-terminal devices (with S, I, and F denoting a superconductor, an insulator, and a ferromagnetic metal, respectively), whose principle of operation is based on a nonequilibrium superconducting state driven by tunnel injection of quasiparticles. Using the F layer makes the device asymmetric and considerably improves input–output isolation in comparison with the formerly investigated symmetric S1IS2IS3 devices.
