	<span lang="EN-US">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 Li<i><sub>x</sub></i>Zn<sub>0.6-2<i>x</i></sub>Cu<sub>0.4</sub>Fe<sub>2</sub>O<sub>4</sub> (<i>x</i> = 0.05, 0.1, 0.15, 0.2, 0.25, 0.3)
at different chemical reaction temperature (100¡æ, 125¡æ and 150¡æ) 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 &Aring; to 8.4653 &Aring; . 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 <i>x</i> ¡Ý 0.2 when the chemical reaction
carried at 125¡æ and 150¡æ and exhibits super paramagnetic structure for all
the composition prepared at 100¡æ. The samples <i>x</i> ¡Ü 0.2 shows multidomain structure for all the samples prepared at
125¡æ and 150¡æ. The Curie temperature obtained using the susceptibility data
are found to be in the range 350¡æ to 700¡æ. An attempt has been made to
synthesis the nanoparticles at lower reaction temperature by using
non-conventional microwave sintering method.</span><span lang="EN-US"><?xml:namespace prefix = o /><o:p></o:p></span>
