Effects of Mn ions on structural and Mossbauer properties of nanoferrites Zn(1-x)MnxFe(2)O(4)by sol-gel combustion method

Zn1-xMnxFe2O4(x=0, 0.15, 0.25, 0.35, 0.45, 0.55, 0.75, 0.85) ferrites were synthesized by sol-gel combustion method with citric acid as complexing agent, and mole ratio of metal ions and pcitric acid is 1:1. All samples were sintered by 550 degrees C. The structural and magnetic properties of MnZn ferrites were studied. The XRD analysis shows that the structure of samples are cubic spinel ferrite. The SEM analysis shows the samples particles are sphere and agglomeration. The Mossbauer Spectrum analysis shows that the paramagnetic double lines spctra gradually change Zeeman six lines spectra.
