FIG. 1.

(a) (b) Low and higher magnification SEM micrographs of MGNFs displaying a crumpling and branching morphology. Each graphene flake has a wedge like structure with a 2 nm or less thick edge and a progressively thicker base; (c) The cross-section demonstrates the vertical orientation of the MGNFs; (d) SEM micrograph of MGNFs irradiated with an ion dose of 1017 ions/cm2.

FIG. 2.

(Color online) Raman spectra of multilayer graphene nanoflakes implanted with N-doses of 0 (pristine) to 1017 ions/cm2. The non distinguishable D and G peaks and absence of G’ peak at 1015 ions/cm2 indicate augmented amorphisation.

FIG. 3.

(Color online) Magnetic response of nitrogen implanted graphene nanoflakes with doses of 0 to 1017 ions/cm2 (a) Magnetic moment M as a function of field H at temperatures of 5 and 300 K for a MGNF implanted with 1013 ions/cm2. Symbols represent the measurements and the line represents the fitted Brillouin curve at 5 K using J = S = 1 and g = 2 values. (b) Magnetization values normalized by the sample area as a function of implantation dose measured at temperatures of 5 and 300 K. (c) Effective magnetic moment per implanted N-ion as a function of implantation dose.
