Total current J, current spin polarization p and TMR each as a function of the bias voltage for different values of φ. tLR = 0 in Figs. (a) to (c) and tLR = 0.01 in Figs. (d) to (f). The other parameters are intradot energy level εd = 0, temperature T = 0.01, and polarization of the leads PL = PR = 0.4.
