Figure 7

Total (black line) and projected (red line) density of states of the Co-B-AGNR, Co-C-AGNR, Co-D-AGNR, and Co-E-AGNR under different magnetic configurations. (a) and (b) are the spin-polarized results associated with AFM and FM magnetic configurations, respectively. Spin-up and spin-down states are denoted by positive and negative values, respectively. The Fermi level is set to zero.
