(Color) (a) Scheme of the spin valve. Ferromagnetic layers induce in each superconductor through proximity effect an exchange field whose relative orientation is controlled by an externally applied magnetic field. (b) The exchange fields are confined to the plane, and are misaligned by an angle .
(Color) (a) Current vs bias voltage for several angles at and . (b) Differential conductance vs calculated for the same values as in (a).
(Color) (a) Nonequilibrium tunnel magnetoresistance ratio ∣TMR∣ vs calculated for several angles at and . Gray regions correspond to voltage intervals of very large TMR. (b) ∣TMR∣ vs for different values at and .
(Color) (a) Nonequilibrium current polarization vs calculated for several angles at and . (b) vs for different values at and .
