Transmission spectra of spins \(\uparrow \) and \(\downarrow \) under p (solid and dashed) and ap (dash-dotted and dotted) junction in a two-probe junction of 4-ZNR with \(m=5,M=0.1t\) for (a) \({U}^{1}={U}^{2}=0\), (b) \({U}_{5,1}^{1}=t,{U}_{-5,1}^{2}=t\), (c) \({U}_{4,1}^{1}=t,{U}_{5,1}^{2}=-\,t\), and (d) \({U}_{5,1}^{1}=t,{U}_{-5,1}^{2}=-\,t\). The energy bands of a virtual bulk ZNR with supercell the same as region C of the configuration in (c) under p junction are also plotted in (e) for spin spins \(\uparrow \) and in (f) for spin \(\downarrow \).
