Abstract

In this paper, we have reported about the enhancement of magnetization and blocking temperature of the Fe₃O₄-reduced graphene oxide (RGO) nanocomposite, which is formed by embedding Fe₃O₄ nanoparticles onto RGO sheets. We utilized powder X-ray diffraction, field emission scanning electron microscopy, high-resolution transmission electron microscopy, electron energy loss spectroscopy (EELS), energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS) techniques to investigate the crystallinity, morphology, phase, composition, purity, and evolution of oxidation states of nanosized Fe₃O₄ (S1) and Fe₃O₄-RGO nanocomposite (S2). EELS, Raman, and XPS all together indicate that GO is converted into RGO during the formation of the Fe₃O₄-RGO nanocomposite. Analysis of Fe 2p_3/2 and Fe 2p_1/2 peaks in the XPS spectrum of S1 and S2 reveals that Fe²⁺ ions are converted to Fe³⁺ ions during the formation of the Fe₃O₄-RGO nanocomposite, which has been proposed as the main reason for enhancement in magnetization. Enhancement of the blocking temperature of S2 with respect to S1 is due to the enhancement in the size of the magnetic domain in S2.
