ESR study of a SWCNT thin film.
(a) ESR signals of the SWCNT thin film at H⊥. The solid lines show the data measured at 15 K (upper), 60 K (center) and 290 K (bottom). The symbols of circles (upper), triangles (center) and squares (bottom) show the least-squares fits with a Lorentzian lineshape to the observed ESR signals. (b) Temperature dependence of the spin susceptibility χ (main panel) and the inverse spin susceptibility 1/χ (inset) of the ESR signal of the SWCNT thin film at H⊥. The solid lines show the least-squares fits with the Curie law to the data. (c) Temperature dependence of the full width at half maximum, ΔH1/2, of the ESR signal of the SWCNT thin film at H⊥.
