Abstract :

In this study, we report the behavior of maximum energy product (BH)max of cobalt ferrite nanopowder towards the variation of calcinations temperature. The studied CoFe2O4 nanopowder was synthesized using solgel autocombustion method. X-ray diffraction, scanning electron microscopy, Mössbauer spectroscopy and superconducting quantum interference device magnetometer techniques were used to characterize crystal structure, phase composition, morphology and magnetic properties. By changing the calcination temperature (T= 600°C, 800°C, 1000°C and 1100°C), the structural and magnetic properties of the compounds could be tuned. The magnetic properties results show that the highest value of (BH)max is close to 0.35 MGOe observed for the sample calcined at T=800°C. These results suggest that (BH)max of cobalt ferrite nanopowder can be enhanced by optimizing synthesis steps.
