“…Wu et al [32] synthesized Ni 0.5 Zn 0.5 La x Fe 2–x O 4 using solid-state reaction at low temperatures for the first time. The results showed that the calcination temperature affects the magnetic properties of lanthanum substituted Ni-Zn ferrite, while the highest coercivity value of 120.09 Oe obtained at 800°C of calcination temperature.…”

Lanthanum substituted Ni-Zn ferrite nanoparticles (Ni0.5Zn0.5LaxFe1-xO4; 0.00 ≤x≤ 1.00) synthesized by sol-gel method were presented. X-ray diffraction patterns reveal the typical single phase spinel cubic ferrite structure, with the traces of secondary phase for lanthanum substituted nanocrystals. In addition, the structural analysis also demonstrates that the average crystallite size varied in the range of 21–25 nm. FTIR spectra present the two prominent absorption bands in the range of 400 to 600 cm-1 which are the fingerprint region of all ferrites. Surface morphology of both substituted and unsubstituted Ni-Zn ferrite nanoparticle samples was studied using FESEM technique and it indicates a significant increase in the size of spherical shaped particles with La3+ substitution. Magnetic properties of all samples were analyzed using vibrating sample magnetometer (VSM). The results revealed that saturation magnetization (Ms) and coercivity (Hc) of La3+ substituted samples has decreased as compared to the Ni-Zn ferrite samples. Hence, the observed results affirm that the lanthanum ion substitution has greatly influenced the structural, morphology and magnetic properties of Ni-Zn ferrite nanoparticles.

Improvement of NiZn ferrites properties by means on Ni/Zn content ratio modification and by partial substitution of Fe 3+ ions by La 3+ ions is presented. NixZn1−xFe2O4 and NixZn1−xLa0.02Fe1.98O4 samples of small particles were prepared by self-propagated combustion method. X-ray spectroscopy was used for structural analysis, temperature dependence of magnetic susceptibility was used for evaluation of chemical and phase composition. Analysis showed that pure spinel structure without secondary phase caused by La ions for all values of Ni/Zn content was present. Noticeable growth of the magnetic susceptibility at room temperature was observed with rising of Zn 2+ ions content.

“…Nickel-doped zinc ferrite has been the subject of intense research in recent years due to their wide range of scientific and technological applications like highfrequency applications especially for multilayer chip inductors, transformers, and electronics due to the presence of properties such as saturation magnetization and high permeability [3,4]. The magnetic and electronic properties of ferrites depend very much on stoichiometry and synthesis mechanism.…”

A series of magnesium-doped Ni 0.65−x Mg x Zn 0.35 Fe 2 O 4 (x = 0.00, 0.04, 0.08, 0.10, 0.12, 0.16) ferrites have been synthesized using sol-gel and solid-state techniques. Sol-gel-synthesized ferrites were sintered at 1000 • C/2 h whereas solid-state-prepared ferrites were sintered at 1250 • C/2 h. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) studies confirm the spinel phase, and cation ion distribution has been estimated for both the batches using these studies. Magnetic measurements indicate the increase of saturation magnetization (M s ) up to x < 0.10 and decreases for further increase in concentration of magnesium. The Curie temperature of the samples was found to be decreasing with increase in concentration of Mg 2+ ions in both the batches.
