The effect of Zn-Ti substitution on the infrared spectroscopy, elastic, dielectric, and resistivity properties of CoZn x Ti x Fe 2−2x O 4 ferrites (where x = 0.0-0.4 in steps of 0.1) is investigated in the paper. All the samples were synthesized by the sol-gel method. Infrared spectroscopy shows two major absorption bands indicating that the prepared samples are in spinel structure. Elastic properties and dielectric properties are measured at room temperature and Zn-Ti is substitution dependent. The dc resistivity is measured using a two-probe method in the temperature range 300 to 650 K. The dielectric constant decreased whereas dc resistivity increased with the Zn-Ti substitution. The elastic constant decreases with increases in Zn-Ti ions.

“…As integral microwave components, phase shifters have been demonstrated miniaturization using LTCC ferrite tapes [1][2][3][4][5]. One member of gyromagnetic materials, LiZnTi ferrites have been investigated and applied in phase shifters due to their high Curie temperature, excellent temperature stability, high remanence square ratio, wide range of saturation magnetization, and low cost [6][7][8][9][10][11][12][13][14]. However, these ferrites prepared by traditional methods need to be sintered above 1100°C to achieve high densification and uniform grain size distribution.…”

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.
