(Color online) Spin-dependent transmission probability τ _σ (logarithmic scale), spin-dependent Seebeck coefficient S _σ , and spin-dependent Lorenz number L _σ (in units of $L_{WF}=\frac{{\pi }^2{k}_B^2}{3e^2}$ as functions of the chemical potential μ under different values of ϕ at room temperature (T = 300 K). The black solid (red dashed) lines in (a n), (b n) and (c n) (n = 1,..., 6) represent spin-up (spin-down) transmission probability, spin-up (spin-down) Seebeck coefficient, and spin-up (spin-down) Lorenz number, respectively.
