Structural properties of nickel-substituted cobalt ferrite nano-particles NixCo1-xFe2O4 (x=0.2,0.8) synthesized using two different methods, namely combustion and co-precipitation are studied. The structural parameters of Nickel-substituted Cobalt ferrite nano-particles confirm the formation of nano-sized particles of cubic spinel structure. Lattice parameters, density, particle size and inhomogeneity are determined while Attenuated total reflectance (ATR-IR) spectroscopy and scanning electron microscope images are studied. The ATR-IR spectra show transmission peaks, in the range around 600cm-1and 400 cm-1which respectively arise from tetrahedral and octahedral interstitial sites in the spinel lattice and found cationic exchanges between the lattices of these sites. The studies reveal that the sol-gel auto combustion method can be preferred to the co-precipitation method for producing single phase nano particles with smaller crystallite size.

Abstract
Structural properties of nickel-substituted cobalt ferrite nano-particles NixCo1-xFe2O4 (x=0.2,0.8) synthesized using two different methods, namely combustion and co-precipitation are studied. The structural parameters of Nickel-substituted Cobalt ferrite nano-particles confirm the formation of nano-sized particles of cubic spinel structure. Lattice parameters, density, particle size and inhomogeneity are determined while Attenuated total reflectance (ATR-IR) spectroscopy and scanning electron microscope images are studied. The ATR-IR spectra show transmission peaks, in the range around 600cm-1and 400 cm-1which respectively arise from tetrahedral and octahedral interstitial sites in the spinel lattice and found cationic exchanges between the lattices of these sites. The studies reveal that the sol-gel auto combustion method can be preferred to the co-precipitation method for producing single phase nano particles with smaller crystallite size.
