| چکیده | ||
| Fe3O4/MWNT magnetic nanocomposites was synthesized by a facile solvothermal route. Distribution of Ferrous and Ferric cations among the two interstitial (tetrahedral and octahedral) sites has been estimated by applying the full pattern fitting of the Rietveld refinement methods. This analyse indicated that Ferrous cations occupy tetrahedral sites. Raman spectroscopy (RS), scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FT-IR) confirmed the formation of the ferrite structure on the external surfaces of the CNTs. Vibrating sample magnetometer (VSM) measurement indicated that this nanocomposite at room temperature was treated as superparamagnetic material with high saturation magnetization. | ||
