Role of Glycine-to-Nitrate Ratio in Physical and Magnetic Properties of Zn-Ferrite Powder

Abstract

     We report  the influence of different glycine-to-nitrate ratios on the physical and magnetic properties for synthesized zinc-ferrite by  microwave-assisted combustion route. Phase impurity and surface morphology investigated with XRD analysis and field emission- scanning electron microscopy, indicated that  spinel structure  were  formed.Average particles size increased  with the decrease of glycine to nitrate ratio. Magnetic measurement  results indicated that  high values of saturation magnetization  were produced with low  glycine/nitrate ratio. Optical properties of  the investigated ferrites exhibited photo absorption from UV to visible region with  energy gap values that decreased  with the decrease of glycine-to-nitrate ratio. Mainly two broad metal-oxygen bands for zinc-ferrite  were seen in FT-IR spectra.
