Investigation of annealing effects on the physical properties of NiZnFeAlO ferrite.

In the present study, the structural, morphological, electrical, and dielectric properties of NiZnFeAlO annealed at 600 °C, 900 °C, and 1200 °C were investigated. The X-ray diffraction patterns confirmed the presence of the single-phase cubic spinel structure with the 3̄ space group. The SEM images of NiZnFeAlO nanoparticles demonstrated that these samples (Ni900 and Ni1200) were nano-sized and that the increase in annealing temperature enhanced the agglomeration rate.
