Decoration of Carbon Nanotubes with CoO and Co Nanoparticles
Figure 8
(a) A comparison between the 59Co NMR spectra for samples annealed at 500°C and 700°C, as measured at 300 K. (b) 59Co NMR spectra at selected temperatures for both samples. The inset shows the temperature dependence of the Larmor frequency , that is, the local magnetic moment, for the unfaulted fcc structure.
