Possible magnetic performances of graphene-oxide and it's composites: A brief review

Abstract

Carbon-based nanostructured materials are very promising for spintronic applications due to their weak spin-orbit coupling and potentially providing a long spin lifetime. Nanostructured carbons are not magnetic materials, but intrinsic magnetic behavioral nanostructure carbon materials could be fabricated through qualitative alterations. On alterations of carbon nanostructured materials, it changes their critical temperature and magneto-crystalline anisotropy energy that could be useful as favorable magnetic materials for different magnetic/electromagnetic device-based applications. Different processes are used for the alteration of nanostructure carbon materials like chemical doping, introducing defects, changing the density of states, functionalization, intercalation, forming heterostructure and fabricating nanocomposites layered semiconductor materials. Among the carbon-based derived nanostructured materials, the graphene oxide (GO) gets attracted towards the magnet forming in the spin-like structure across the area of the magnet. Due to its magnetic behaviour, it is used for the adsorption of metals and radionuclides and to make nonconductive oxide-metal. In this review article, the basics of magnetic behavioral change of the carbon-based GO/GO-nanocomposites nanostructured materials are described by gathering information from the literature that were/are reported by different researchers/research groups worldwide.
