Synthesis, structural and magnetic properties of NiO nanospheres and rGO-NiO nanocomposites and observing magnetocaloric effect in rGO-NiO nanocomposites

NiO nanospheres and NiO nanospheres deposited on rGO nanosheets i.e., rGO-NiO nanocomposites have been synthesized using in-situ solvothermal method. The crystal structures, phases, and morphologies of the synthesized samples have been confirmed by XRD, Raman, and TEM measurements. The detailed information regarding chemical bonding, identification of the constituent elements and their binding chemical states in the synthesized nanocomposites...
