Abstract
Magnetic graphene-oxide has recently taken in research spotlight due to its extraordinary physical and chemical properties. Here, we report the synthesis of Graphene oxide based magnetic nano-composites with the size of (~13-14 nm) using simple chemical co-precipitation method. The composites were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and vibrating sample measurement (VSM). It was observed that all the composites are superparamagnetic in nature. The saturation magnetization was observed to increase with the increasing magnetite nanoparticles (MNPs) in the composites. The dielectric properties of the composites were also improved by adding MNPs. These results remark that synthesized nanocomposites have great potential for magnetic, capacitive, microwave absorption and bio medical applications such as drug delivery, tumor treatment etc.
