“…Variation in coercivity "H c " of spinel ferrites is strongly dependent on crystalline size; there is inverse relation between crystalline size and coercivity "H c " of spinel ferrites, same behavior is reported in literature [11]. This inverse relation between coercivity and crystalline size can be observed clearly from figure 3.…”

“…It is already reported that magnetic and electrical properties of ferrites have inverse relation with crystalline size [7]. To synthesize ferrites in nano-scale, there are a number of synthetic approaches to synthesize nanoferrites such as sol-gel [8][9][10][11], micro-emulsion [3], solid state [12], micro wave sintering [13], novel combustion [14], two step direct micro-emulsion [15], co-precipitation [16,17], hydrothermal [18], mechano-chemical [19] etc.…”

“…The fact that the coercivity of the synthesized ferrites decreases linearly with Zn concentration can be utilized to tune magnetic properties for a desired application. Observed variation of M max with Zn content suggests that, M max one can selectively tune the initial permeability, a vital parameter for MLCI applications 12 .…”

Single phase nanocrystalline soft magnetic Mg 0.7-x Ni 0.3 Zn x Fe 2 O 4 , ferrites with x = 0.0 -0.7 were prepared by sol gel auto-combustion method. X-ray diffraction confirms the formation of single phase nano-crystalline cubic spinel ferrites with average grain diameter ranging between 12.9 nm to 23.9 nm. Formation of the ferrite phase without subsequent heat treatment makes sol-gel auto combustion technique especially suitable and economical for the large scale industrial production of the nano-crystalline ferrites for multilayer chip inductor applications (MLCI). Both, lattice parameter and X-ray density shows a linear increase with increasing Zn 2+ concentration, attributed to the difference in ionic radii and density of Mg and Zn. Increase in Zn content enhances the soft magnetic behavior, exhibiting linear decrease of coercivity from 122.34 Oe to 72.45 Oe, explained by increase of density with Zn addition. The maximum magnetization (M max ) increases up to 0.106 Tesla (for x = 0.4) and. then decreases with increase of Zn content, discussed on the basis of increase of the occupancy of A-site in spinel ferrite by non-magnetic Zn 2+ ion.

“…Among the various elements incorporated in the Ni-Zn ferrite system, not a significant amount of work is focused on Mg 2+ ion substitution. It has been found from the work of different researchers that the Mg 2+ ion-substituted ferrite system shows enhancement in properties such as improved saturation magnetization and resistivity, reduction in power loss, and also good thermal stability [6][7][8][9]. Hence, the work in this paper is focused on tailoring this composition by substituting various concentrations of Mg 2+ ions in the place of Ni 2+ ion to study the effect of magnesium on electrical and magnetic properties.…”

The effect of magnesium substitution in Ni-Zn ferrites (Ni 0.80−x Mg x Zn 0.20 Fe 2 O 4 , where x = 0, 0.10-0.50) was studied on its electrical and magnetic properties. Ni-Mg-Zn ferrites were synthesized by novel combustion method, followed by calcination at 900 • C. The X-ray diffraction (XRD) pattern shows that the prepared sample was a single-phase spinel cubic structure, and the calculated crystallite sizes were found to be in the range 44-48 nm. Fourier transform infrared spectroscopy (FTIR) spectra confirm the tetrahedral and octahedral modes of vibrations. The observed saturation magnetization values range from 37 to 63 emu/g for magnesium-added Ni-Zn ferrites. The increase in resistivity was observed with the addition of magnesium ions except for the concentration of x = 0.50. The change in dielectric behavior with respect to composition and frequency were studied.
