Abstract

In this work, CoFe2O4 nanostructure was synthesized from Cobalt and ferric nitrates and sodium hydroxide (NaOH) by hydrothermal method. Effect of PH on the structural and magnetic properties of the resulting powder was studied at calcination 400°C and 600°C. The resulted products were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), Fourier transformed infrared (FTIR), and vibrating sample magnetometer (VSM) technique   as synthesis , when calcination at  400°C and 600°C with different PH . The reduction in crystallite size that their average crystallite size is found (13.98-22.17) nm crystallite size at PH=9 higher than when PH=3. The FE-SEM images indicated that particles were agglomerated and spherical shape and size between (23.6 - 57.9) nm for PH=9 and (23.3 – 114.6) nm for PH=3. The created CoFe2O4 nanostructure have demonstrated ferromagnetic behavior for all the samples behavior which was found in VSM results examination.
