Impact of Zn addition on structural, morphological, and magnetic properties of thermally annealed Li–Zn nanoferrite

Résumé

The effect of Zn addition on cationic distribution, structural and magnetic properties of nanocrystalline Li-Zn ferrites are reported. Xray diffraction confirms the formation of spinel nanoferrites with an average grain diameter of 34 -82 nm. The addition of Zn results in a linear increase of lattice parameter and X-ray density. Magnetism in the studied samples is governed by the Yafet-Kittel three-sub-lattice model, shown by a non-zero canting angle. The variation in magnetic properties is correlated with the calculated cationic distribution. A new antistructural modeling explains the changes in the concentration of donor and acceptor surface active centers.
