(a) Band structure of FM 6-ZSiNR. The spin-up and spin-down components are presented in red and blue lines, respectively. (b) and (c) Spin density for 6-ZSiNR with P and AP configurations under zero bias. The two electrodes have parallel spin configuration in the P case but antiparallel spin configuration in the AP case. Pink and blue surfaces denote the spin-up and spin-down components, respectively. The isosurface corresponds to 0.01 e /Å3. (d) I – V curves for the P and AP configurations. Inset is a semi-logarithmic scale plot. (e) Spin up, spin down, and total magnetoresistance on a semi-logarithmic scale. (f) and (g) Band structures for left and right electrodes, and transmission spectra for P (f) and AP (g) configurations under zero bias. Solid and open circles denote π and π * states. Solid arrows indicate allowed transmissions, and dashed arrows indicate forbidden transmissions. G 0 equals e 2/ h . Reproduced with permission from Ref. [ 36 ].
