Abstract

Li_0.1Zn_0.9O and MgFe₂O₄ powders were synthesized using chemical methods and mixed in different proportions to prepare a mixture of Li_0.1Zn_0.9O and MgFe₂O₄ that was thermally treated between 900 to 1100 °C for 1 hour. Structural characterization was done using X-ray powder diffraction measurements. Grain sizes and morphologies of Li_0.1Zn_0.9O, MgFe₂O₄, and Li_0.1Zn_0.9O+MgFe₂O₄ samples were observed using a scanning electron microscope. Variation of magnetic properties of the Li_0.1Zn_0.9O+MgFe₂O₄ samples due to the addition of Li_0.1Zn_0.9O was studied in relation to the structural changes occurring due to the thermal treatment. In particular, changes in the cationic distribution between the tetrahedral and octahedral positions were studied with respect to the increase of the annealing temperature. Magnetization was found to be dependent on the cations distributed in the tetrahedral and octahedral sites of the MgFe₂O₄.
