Abstract
The present study describes the morphological and structural characterization of nanosized Ni-Mg cobalt-ferrites. The nominal compositions Co0.5Ni0.5−xMgx Fe2O4 in the range (0.0 ≤ x ≤ 0.5) have been synthesized by co-precipitation method. These nanopowder products were sintered in furnace at temperature of 900°C for 10 hour with a heating rate of 5°C/min to obtain these ferrites. The prepared nanoferrites were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) with varying concentration (x) in the composition of the prepared nanoferrites. XRD confirmed formation of single phase spinel ferrite with average crystalline size in the range of 34–37 nm. Lattice constant (a) increases with an increase of Mg concentration. Further information about the structure and morphology of the nanoferrites was obtained from FESEM and results are in good agreement with XRD.
