Abstract
A nitrate–citrate gel was prepared from metal nitrates and citric acid by sol–gel auto combustion process, in order to synthesize NiFe 2O 4 ferrite. X-ray diffraction showed the formation of NiFe 2O 4 and the inclusion of α-Fe 2O 3. However, with increasing the calcination temperature, this inclusion phase (α-Fe 2O 3) decreased. TEM was also used to characterize the microstructure of the nanosize NiFe 2O 4. Magnetization hysteresis of the nickel ferrite powders was performed at room temperature. It is shown that this powder which is composed of crystalline NiFe 2O 4 monophase, exhibited M s = 54 (emu/g) at magnetic field of 2 (kOe).
