Local density of state and charge difference of Ru in (a) Ideal 16, (b) SISF, (c) SISF2, and (d) SESF models, respectively. The local density hybridization of Ru occurs in SESF structures with its neighboring Ni. Charge accumulation of Ru with its 12 nearest neighbor atoms is illustrated. The iso-surface is 0.008 eV/Å. Ni1 and Ni2 are the nearest neighbor Ni atoms of Ru.
