Characterization of nanosized NiZn ferrite powders synthesized by an autocombustion method

Nanocrystalline Ni0.5Zn0.5Fe2O4 with average particle size of ∼9 nm has been synthesized by an autocombustion method and characterized by powder XRD, TEM and room temperature magnetic measurements. High room temperature magnetization comparable to that of the bulk material is obtained for the nanosized powders annealed at 800 °° C, with a maximum particle size of ∼54 nm. The results show that optimum properties can be achieved for NiZn ferrite powders synthesized by the present autocombustion method and processed at relatively lower temperatures.
