Ni1-xFexO (x = 0.00, 0.01, 0.02, 0.03, 0.04) samples were successfully synthesized by co-precipitation method. Room temperature structural properties were analyzed by PXRD studies and Rietveld profile refinement technique. The structural results revealed that the samples assigned by cubic symmetry with Fm3m space group. Effects of structural properties with respect to the Iron substitutions in NiO matrix was investigated. Charge density profiles of the prepared materials were also investigated by maximum entropy method. From MEM analysis, it found that the ionic nature of Ni-O bond decreased. The surface morphologies were determined by scanning electron microscopic (SEM) measurements.
