| Abstract: | Taking into account the exchange splitting in ferromagnet, two insulating barrier scattering, and quantum interference effects, we calculate the differential conductance and shot noise in ferromagnet/insulator/ferromagnet/insulator/s-wave superconductor structure. It is shown that both the differential conductance and the shot noise oscillate with the length of intermediate ferromagnetic layer. |

| Keywords: | differential conductance shot noise oscillatory effect |
