Lithium ferrites have attracted
considerable attention because they have been used as replacements for garnets
due to their low cost. A series of polycrystalline ferrite samples with the
composition of LixZn0.6-2xCu0.4Fe2O4 (x = 0.05, 0.1, 0.15, 0.2, 0.25, 0.3)
at different chemical reaction temperature (100℃, 125℃ and 150℃) were
prepared using non-conventional microwave sintering method. The
characterization was carried out using X-rays technique. The X-ray analysis
confirms the formation of single phase cubic structure. The lattice parameter
ranges from 8.3690 Å to 8.4653 Å . The X-ray density shows the variation as a
function of temperature of synthesis. The variation of AC susceptibility with
temperature shows the existence of single domain structure for x ≥ 0.2 when the chemical reaction
carried at 125℃ and 150℃ and exhibits super paramagnetic structure for all
the composition prepared at 100℃. The samples x ≤ 0.2 shows multidomain structure for all the samples prepared at
125℃ and 150℃. The Curie temperature obtained using the susceptibility data
are found to be in the range 350℃ to 700℃. An attempt has been made to
synthesis the nanoparticles at lower reaction temperature by using
non-conventional microwave sintering method.
