Cation Distribution Tuning of Solution Combusted CoF 04 Powders

In this worA; the different fuels (citric acid, glycine and urea) were usedfor solution combustion synthesis of CoFe204 powders. X-ray diffraction, Raman spectroscopy, electron microscopy and vibrating sample magnetometry techniques were employed for characterization of phase evolution, cation distribution, microstrocture and magnetic properties of the as-combusted CoFe204 powders. Single phase CoFe204powders with partially inverse strocture in which the Co2+ cations are distributed in both tetrahedral and octahedral sites were synthesized by the citric acid, glycine and urea foels. The as-combusted CoFe204 powders by the citric acid fuel exhibited the highest inversion coefficient. The crystallite size of the as-combusted CoFe204 powders synthesized by ureafoel was 15 nm, increased to 41 and 52 nm for the glycine and citric acid foels, respectively. Furthermore, the solution combusted CoFe204 powders showedferromagnetic behavior with saturation magnetization of 61.9, 63.6 and 41.6emulgfor the citric acid, glycine and urea foels, respectively. The high crystallinity and particle size of the as-combusted CoFe204powders using glycine fuelled to the highest magnetization and the moderate coercivity
