Enhanced electrical and magnetic functionality of Ni-Zn-co-doped CoFeO rGO nanocomposites.

Enhancement in electrical and magnetic functionalities of rGO CoFeO and CoZnFeNiO nanocomposites was identified compared to their spinel-type metal oxides. Moreover, changes in morphology that occurred during the formation of the composites were fabricated a simple hydrothermal route. Electron microscopic investigations confirmed that the microspheres of the metal oxides were constructed by porous nanolamellae comprising nanoparticles interconnected to form highly stable porous microspheres.
