Spin dynamics in graphene-like nanocarbon, graphene and their nitrogen adatom derivatives

Ulterior computational device is atomic electron in which information route would be precision spin gyration. This demands to investigate spin dynamics in realistic graphene. Our scenario presents spin transport data obtained using electron spin resonance spectroscopy, over 123–473 K for graphene, graphene-like nanocarbon (GNCs) and their nitrogen (N)-doped derivatives. Variations in dispersion widths and anisotropy in effective g-factor indicated modifications in spin–lattice, and spin–spin relaxation time, for both systems after N loading. Particularly, for GNCs contributions of orbital moments to spin inhomoginities are reduced. It resembles with variations observed for spin–orbit coupling constant and spin-flip factor. Flip of spin is more favorable, for N-GNCs, due to retardation in momentum- and spin relaxation rate. Nitrogen narrowed down mid gap states in GNCs and has profound impact on modifications in pseudo chemical potential with reduced density of states, effective magnetic moment, and spin and defect concentration. The variations in spin parameters are opposite, especially, for N-graphene. The spin susceptibility indicated that, there are ~ 10 non-interacting spins per 100 carbon atoms in graphene, and GNCs which is reduced by 50%, especially, for spin correlated, N-GNCs. Atomically engineered spin degrees of constraints are useful for spintronic applications.
