In this research, we investigate the effect of carbon nanotubes (CNTs) as a substrate on the morphology, size, magnetic behavior, and band gap energy (Eg) of nickel ferrite nanoparticles. Synthesis of NiFe2O4 nanoparticles carried out using a direct co-precipitation method in aqueous solution containing carbon nanotubes. The samples were characterized using X-ray diffraction (XRD), scanning […]
