Title: Structural, dielectric and magnetic behavior of nanocrystalline zinc substituted magnesium ferrite

Zinc substituted magnesium ferrites Zn{sub 0.2}Mg{sub 0.8}Fe{sub 2}O{sub 4} and Zn{sub 0.4}Mg{sub 0.6}Fe{sub 2}O{sub 4} were prepared by sol-gel auto combustion method. Rietveld profile refinement of the XRD patterns confirms the formation of a cubic spinel structure in single phase. The dielectric properties viz. dielectric constant and dielectric loss tangent tanĪ“ increase with increasing temperature. The dielectric behavior is explained by using the mechanism of polarization process, which is correlated to that of electron exchange interaction. The saturation magnetization, coercivity and remanent magnetization decreases appreciably with increase in Zn which could be attributed to change in cation distribution.
