“…Figure 4 shows the spin-specific electronic transmittance curves of the Ni n /ZGNR systems and the pristine nanoribbon, and figure 5 the DOS projections on the Ni s, p and d orbitals. Fe analogs; the only difference of note is that around the Fermi level there is a somewhat wider energy window with no loss of transmittance, there being no Ni states closer than 0.2 eV to the Fermi level (similar behavior was reported by Rigo et al [52] for a Ferro-F Ni/ZGNR system). However, although Ferro-F Ni 3 /ZGNR and Ferro-F Ni 4 /ZGNR behave like Ferro-A Ni 3 /ZGNR and Ferro-A Ni 4 /ZGNR at energies at which the pristine ZGNR has multiple transmission channels, showing little or no transmittance loss at these energies, their spin-down transmittance is significantly reduced near or around the Fermi level due to d-type spin-down DOS peaks.…”

“…in systems in which a finite ZGNR segment bearing a single adstructure was sandwiched between two semi-infinite ZGNR leads. Calculations with single Fe or Ni adatoms were included for comparison with the larger clusters and with the results of Rigo et al [52]. Since our aim was to explore the possibilities of clusters rather than to carry out an exhaustive analysis, and given the heavy computational burden of these calculations, we did not perform calculations for all possible cluster configurations at all possible adsorption sites, but instead concentrated on lateral sites (where the adstructures bind more strongly) and configurations obtained in previous work [42,44].…”

“…Furthermore, we restrict ourselves to so-called hole defects, i.e. adatoms which sit over the center of a hexagon 45 . Denoting by ρ the fraction of randomly chosen hexagons which have an impurity atop their center, we assume that hopping along all six bonds which make such a hexagon is characterized by SO couplings V ij as given in Eq.…”

“…29 This leads to impurity distributions heavily weighted towards the edge sites -an observation confirmed elsewhere in the literature. [30][31][32][33][34][35][36] In addition to the binding energy, the magnitude of the magnetic moment on an impurity atom should also depend on impurity position. We shall demonstrate here that the principal features of this dependence derive from the underlying electronic structure of the GNR host.…”
