Effect of rotational speed on structural and magnetic properties of cobalt ferrite substituted aluminium ions using coprecipitation method

Abstract

The synthesis of Al-doped cobalt ferrite has been successfully carried out by the coprecipitation method. The synthesis method with varying rotational speeds aims to find the best characteristics for applications in military industrial technology, such as anti-radar detection materials. Variations in rotational speeds in the titration stage were followed by annealing at 1000°C for 3 hours. The results of this study found that all samples have a cubic structure, have two absorption peaks as octahedral and tetrahedral sides, and all samples are ferromagnetic, so they have the potential to be good anti-radar detection materials. Another finding is that samples without rotational speed are soft magnetic, which is most suitable for anti-radar detection applications.
