“…Lithium ferrites form an important class of materials exhibiting high Curie temperature, high resistivity, high saturation magnetization etc. They are used in various device applications such as telecommunication and microwave device [4, 5, 6, 7]. Recently, with the development of telecommunications, ferrites with high permeability and high frequency stability are widely used to produce all kinds of broadband elements.…”

The effect of sintering temperature (T S ) on the structural and magnetic properties of Li 0.15 Ni 0.3 Zn 0.4 Fe 2.15 O 4 is investigated and discussed. The sample is synthesized by the sol-gel auto combustion method and sintered at 1373–1573 K for 5 h. Phase identification of the powder sample was performed by using the X-ray diffraction (XRD). The XRD patterns confirmed the formation of single phase cubic spinel structure. The bulk density is correlated with T S . From the energy-dispersive X-ray spectroscopy study, it is observed that the percentage of the elements in the component phases is well consistent with the nominal composition of the composites. Field Emission Scanning Electron Microscopy showed that the average grain size (D) is increased with increasing T S . The frequency (100 Hz–120 MHz) dependent complex initial permeability spectra and relative quality factor increased with sintering temperature up to 1523 K then decreased for further increase in temperature. The complex initial permeability has been explained with the help of microstructure, and the redistribution of cations in their sites.
