“…18 Furthermore, Ni-Zn ferrites are characterized by high surface area, chemical stability, high saturation magnetization, high Curie temperature, low coercivity (so magnetic), high permeability, high dielectric constant, low losses, semiconductor dielectric transition and they can nd wide application in the high frequency region of electronics devices. 19 On substitution of Zn 2+ in Ni ferrite the Fe 3+ ions migrate from (A) to [B] site and consequently the Fe A -O-Fe B interaction becomes feeble. Several studies have reported the dependence of magnetic properties of Ni-Zn ferrites on their microstructure, sintering temperature and preparation method, these properties can be changed and tuned by aluminum doping.…”

“…Spinel ferrites have received a lot of attention since their discovery due to their interesting properties and commercial potential. While ferrites refer to ceramics of the general formula AFe 2 O 4 (where A is a divalent cation) that for some applications may be considered as mixed oxides containing hematite (Fe 2 O 3 ), spinels are actually cubic crystalline structures based on the mineral spinel MgAl 2 O 4 [ 1 ]. The so-called normal spinels have the divalent cation (Mg 2+ in the last example) in tetrahedral sites in the crystal lattice and the trivalent cations (Al 3+ in the example) in octahedral sites.…”

Spinel ferrite compounds continue to receive a lot of attention due to their unique properties. Among the numerous synthesis routes existing, the solid-state method was applied for the production of nickel ferrite, by introducing the use of a quartz vial. A mixture of nickel oxide (NiO) and hematite (Fe2O3) was ground and vacuum-sealed in the vial and different thermal treatment programs were tested. The resulting particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectroscopy. For temperatures, below 1000 °C, the solid-state reaction is not complete as nickel oxide (NiO) and hematite (Fe2O3) are still present. The reaction time is a decisive parameter for the morphology of the particles obtained. If, for different reaction times, the particle size distribution is always between 0.3 and 1.7 µm, a longer reaction time leads to the formation of dense, interconnected clusters of particles. Optimal parameters to synthesize a pure phase of spherical nickel ferrite were sought and found to be a reaction temperature of 1000 °C for 72 h.

“…Nanocrystalline ferrites have gained popularity in the field of electronic technology due to their outstanding feature of "ferrimagnetism" [1]. A cubic structure having the standard formula AB 2 O 4 is commonly known as a "spinel" (where A signifies divalent cation and B stands for trivalent cation) [2]. As a result, spinel ferrites can be characterized as tightly packed cubic structures containing iron (Fe 3+ ) as a trivalent cation, yielding the structural formula AFe 2 O 4 .…”

“…Spinel ferrites are extensively used in the fabrication of microwave absorbers owing to their high magnetic losses and huge resistivities [10]. These ferrites are also used in the frequency range of 3-30 GHz [2]. These materials are useful in metallurgical and other high-temperature sectors because they have excellent thermodynamic stability, good electrical conductivity, and high corrosion resistance [11,12].…”

Cerium (Ce)-doped Ni0.5Cd0.5CexFe2−xO4 (0.0 ≤ x ≤ 0.20) was synthesized using the sol–gel auto-combustion method. X-ray diffraction (XRD) analysis revealed that all the samples retained spinel cubic crystal structure with space group Fd3m at 800 °C. Crystal structure parameters, such as lattice constant, average crystallite size, and X-ray density were estimated from the major XRD (311) peak. Bulk density and porosity were also calculated. The average crystallite size was estimated to be in the range of 20–24 nm. SEM images displayed agglomerated particles with a porous morphology. The dielectric constant (ε′) increased and the dielectric loss tangent (tanδ) decreased with rising Ce concentration. The hysteresis loop (M–H loop) was measured at room temperature using a vibrating-sample magnetometer (VSM), which showed a nonlinear decrease in magnetization and coercivity with increasing Ce concentration.
