Structural evolution and magnetic properties of NiCuZn ferrite synthesized via combustion reaction method

We report the fabrication of nickel-copper-zinc (NiCuZn) ferrites via a facile blowing-combustion method, where the grain size and morphology can be readily controlled by adjusting the sintering temperature. The effect of sintering temperatures on the structural evolution as well as the magnetic properties of the NiCuZn ferrites was systematically studied. It's found that the Zn elemental content is highly dependent on the sintering temperature and would undergo evaporation when annealing at 800 degrees C, which consequently greatly affects the magnetic properties of NiCuZn ferrites.

Automated summary

The fabrication of nickel-copper-zinc (NiCuZn) ferrites was achieved through a blowing-combustion method, and the grain size and morphology were controlled by adjusting the sintering temperature. The study systematically investigated the effect of sintering temperatures on the structural evolution and magnetic properties of NiCuZn ferrites. It was found that the Zn elemental content strongly depended on the sintering temperature and evaporation occurred at 800 degrees C, which significantly affected the magnetic properties of NiCuZn ferrites.
