Abstract
Structural characterization and magnetic properties of Zn-substituted Li ferrites with composition$Zn_x;Li_{0.45-x/2}Fe_{2.55-x/2};O_4$ (where x = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5) were studied by varying sintering temperature T S (where T S = 1000, 1050, 1100, 1150, 1200, and 1250 ◦ C) of the six samples. The single-phase cubic spinelstructure was found by XRD patterns and scanning electron microscopy revealed the microstructure of all the samples.Permeability (real, $µ'_i$ and imaginary, $µ''_i$ ) was found to increase with Zn substitution and also with sintering temperature. The real part of initial permeability ($µ'_i$) was found to depend on the density and average grain sizes of thesamples. It was also observed that increase of the real part of permeability was accompanied by decrease of resonancefrequency $(f_r)$ , which confirms the Snoek relation for polycrystalline ferrites.
