“…It is essential that the spinel crystal structure suffers major deformation because of the solubility limit of the large amount of RE substitution; accordingly, specific ratios of dopant were chosen. The effect of neodymium (Nd +3 ) on the magnetic and electrical features of MnZn ferrite was studied by Naik et al , Angadi et al studied the magnetic properties of Sm- and Gd-doped MnZn nanoparticles. Jadhav et al studied Gd-doped MnZn NPs as magnetic carriers for magnetic fluid hyperthermia (MFH).…”

The effect of Er 3+ and Y 3+ ion-co-substituted Mn 0.5 Zn 0.5 Er x Y x Fe 2–2 x O 4 (MZErYF) ( x ≤ 0.10) spinel nanoferrites (SNFs) prepared by a sonochemical approach was investigated. Surface and phase analyses were carried out using SEM, TEM, and XRD. Hyperfine parameters were determined by fitting room-temperature (RT) Mossbauer spectra. Magnetic field-dependent magnetization data unveiled the superparamagnetic nature at RT and ferrimagnetic nature at 10 K. RT saturation magnetization ( M S ) and calculated magnetic moments ( n B ) are 34.84 emu/g and 1.47 μ B , respectively, and have indirect proportionalities with increasing ion content. M S and n B data have a similar trend at 10 K including remanent magnetizations ( M r ). The measured coercivities ( H C ) are between 250 and 415 Oe. The calculated squareness ratios are in the range of 0.152–0.321 for NPs and assign the multidomain nature for NPs at 10 K. The extracted effective magnetocrystalline constants ( K eff ) have an order of 10 4 erg/g except for Mn 0.5 Zn 0.5 Er 0.10 Y 0.10 Fe 1.80 O 4 SNFs that has 3.37 × 10 5 erg/g. This sample exhibits the greatest magnetic hardness with the largest magnitude of H C = 415 Oe and an internal anisotropy field H a = 1288 Oe among all magnetically soft NPs.

“…and trivalent cations are located at octahedral sites. [ 8–10 ] Spinel ferrites of transition metals (e.g., Mn, Mg, Zn, Ni, Co, and Cd) are good candidates for gas sensing due to active interaction of metal oxygen ions and their sensitivity to bond lengths and angles. [ 11–13 ] Transition metal‐containing ferrites (MFe 2 O 4 ) in the nanoscale form are in imperative group of technological materials which has versatile requisition in nuclear magnetic resonance to create cross‐sectional pictures of human body for diagnostic purposes, storage computer memories, drug directing, and magnetocaloric refrigeration application.…”

The zinc ferrite nanoparticles are synthesized by a simple and low cost solid state technique. The synthesized powder is pre‐sintered at 200°C for 5 h and annealing at different temperatures. The crystal structure, phase purity, optical, and morphological analysis studies of synthesized ferrites materiel are investigated by X‐ray diffraction (XRD), scanning electron microscopic (SEM), UV–Visible spectroscopy, and Fourier transform infrared (FTIR) spectroscopic techniques, respectively. The XRD pattern of all zinc ferrite samples shows the formation of single‐phase cubic spinel structure. The optical band gap of zinc ferrite is found to be 1.96 eV. The change in morphology of zinc ferrite is observed due to the effect of the annealing temperature.

A series of nanocrystalline Ni1−xMnxCexFe2−xO4 (x = 0.0, 0.02, 0.04, 0.06, 0.08, and 0.1) were prepared using the citrate auto-combustion method. X-ray diffraction (XRD) indicates that the spinel materials formed in a cubic single phase up to the sample x = 0.02. The average crystallite size is reduced from 61 to 31 nm due to the suppression of grain growth upon cerium occupation at the octahedral site. The cubic spinel structure was confirmed by Fourier-transform infrared (FT-IR) analysis. Scanning electron microscope (SEM) showed agglomerated and rod-shaped structures at various concentrations. AC conductivity and dielectric properties were measured over a frequency range of 20 Hz to 8 MHz. The AC conductivity increases with an enhancement in frequency. The prepared materials have great potential for utilization in microwave devices. The magnetic parameters were estimated from the measured hysteresis loops at room temperature and 100 K using a vibrating sample magnetometer (VSM), which indicated that the samples were suitable for magnetic memory device applications.
