Description
Nano-magnetic magnesium ferrite particles were synthesized by a simple and cost-effective method using different ratios between Mg/Fe precursors and fuel. Significant effects of these ratios on the crystalline phases, crystallite size, particle size, lattice constant, morphological and magnetic properties of the as-synthesized nano-particles have been investigated. Phase evolution, morphological and magnetic characteristics were determined by XRD, SEM, EDX and VSM techniques. The results obtained revealed that the as-prepared Mg ferrite nano-particles have the nanometer size and partially inverse spinel structure. Nano-structured magnesium ferrite spinel has been synthesized with various cyrystallite sizes ranging from 8 to 66 nm. Room temperature magnetization results showed that the magnetic properties of Mg ferrite nano-particles depend upon their size and crystallinity. The saturation magnetization for the sample having the highest crystallite size was 32.85 emu/g. © 2012 Elsevier B.V.
