(Color online) Spin-dependent transmission probability τσ(logarithmic scale) and spin-dependent Seebeck coefficient Sσ as functions of the chemical potential μ in the presence of different values of λ at room temperature (T = 300 K). ϕR and ϕ have same values as ϕR = ϕ = π. The black solid lines represents the spin-up component, and the red dashed lines represents the spin-down component.
