Pure and 2% Mn, Fe and Zn doped NiO nanoparticles were synthesized by co-precipitation method at calcination temperature 550 °C. They were characterized by X-ray powder diffraction, transmission electron microscopy, high-resolution transmission electron microscopy, proton induced x-ray emission, Rutherford Back Scattering, Fourier transmission infrared spectroscopy, UV-vis spectroscopy, M-H loop and electron paramagnetic resonance. The obtained results indicate that the lattice parameter, crystalline size, direct energy gap and chemical functional group are significantly dependent on the kind of dopant element. Moreover, the dopant elements are not affected by the ferromagnetic nature of NiO nanoparticles while g-factor varies according to the kind of dopant elements.
