Pre-ceramic Nanostructured LiZnMn Ferrite Powders: Synthesis, Structure and Electromagnetic Properties

Nanocrystalline powders of LiZnMn ferrite were obtained by the method of solution combustion at various glycine-nitrate ratios (G / N = 0.2, 0.4, ..., 1.4). Elemental analysis showed that the composition of the obtained samples corresponds to the spinel ferrite Li _0.45 Zn _0.05 Mn _0.06 Fe _{2 , 43} O ₄ . Based on the SEM results, it was found that the compositions have a porous microstructure and a developed surface, and the X-ray phase analysis data indicate that the synthesized LiZnMnFe spinel is single-phase and has a high degree of crystallinity (up to 99 & # 37;). It is shown that the magnetic and dielectric characteristics of the obtained samples change systematically depending on the selected redox ratio of the reaction mixture and reach maximum values ??at a stoichiometric value of G / N = 0.6
