Investigation of the Influence of Annealing Temperature on the Structural and Magnetic Properties of MgFe2O4

In this paper, nanocrystalline Mg-ferrites have been synthesized by the low-cost sol-gel auto-combustion method using iron and magnesium nitrates as starting materials. The as-prepared sample was annealed at temperatures of 200°C, 400°C, 600°C, 800°C, and 1000°C in an air atmosphere to investigate the effect of annealing temperature on the physical properties. The structural and magnetic properties of the annealed ferrites were studied using...
