α-Fe2O3/Reduced Graphene Oxide Nanocomposite: Interfacial Effect on the Magnetic Property.

In the present work, the α-Fe2O3/RGO nanocomposite is synthesized by one-pot solvothermal technique. The structural analysis is accomplished using X-ray diffraction and Raman spectroscopy. Temperature and field-dependent magnetic investigation of α-Fe2O3/RGO nanocomposite has been carried out from 350 to 10 K. The transition of magnetic states in α-Fe2O3/RGO hybrid with changing temperature is discussed based on average anisotropy energy and coupling interactions. The ZFC-FC curves are also analyzed to explore the system further. [ABSTRACT FROM AUTHOR]
