“…MnZn nanoferrites are a significant category of soft magnetic materials, and their importance has been increasing because of their good electrical, magnetic, and optical properties; high magnetization, resistivity, and initial permeability; permittivity; low power losses; and coercivity. Due to these advantages, MnZn ferrites are fit for use in transformers/transducers, information storage systems, multilayered chip inductors, sensors, biosensor magnetic fluids, refrigerators, mobile chargers, TVs, desktops, printers, microwaves, ovens, LED bulbs, laptops, juicer mixers, washing machines, mobile phones, drug delivery, MRI, etc. − …”

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.

“…At T B the thermal energy (k B T) equals to energy barrier for magnetic moment reversal associated with the total crystal anisotropy energy (E B = K eff V = k B T). If measurement temperature is above T B , then NPs exhibit SPM phase consistent with the Curie-Weiss law [29]. In SPM phase, the remnant magnetizations or coercivities are not detected.…”

In this study, the samples of the ZnFe2O4 (ZFO) spinel ferrites nanoparticles (SFNPs), Co0.5Ni0.5Ga0.01Gd0.01Fe1.98O4 (CNGaGdFO) SFNPs and (Co0.5Ni0.5Ga0.01Gd0.01Fe1.98O4)x/(ZnFe2O4)y (x:y = 1:1, 1:2, 1:3, 2:1, 3:1 and 4:1) (CNGaGdFO)x/(ZFO)y spinel ferrite nanocomposites (NC) have been synthesized by both sol-gel and Green pulsed laser ablation in liquid (PLAL) approaches. All products were characterized by X-ray powder diffraction (XRD), scanning and transmission electron microscopies (SEM and TEM), elemental mappings and energy dispersive X-ray spectroscopy (EDX). It was objected to tune the magnetic properties of a soft spinel ferrite material with a softer one by mixing them with different fractions. Some key findings are as follows. M-H investigations revealed the exhibition of ferrimagnetic phases for all synthesized samples (except ZnFe2O4) that were synthesized by sol-gel or PLAL methods at both 300 K and 10 K. ZnFe2O4 ferrite NPs exhibits almost paramagnetic feature at 300 K and glass-like phase at very low temperatures below 19.23 K. At RT analyses, maximum saturation magnetization (MS) of 66.53 emu/g belongs to nanocomposite samples that was synthesized by sol-gel method and x:y ratio of 1:3. At 10 K analyses, MS,max = 118.71 emu/g belongs to same nanocomposite samples with ratio of 1:3. Maximum coercivities are 625 Oe belonging to CNGaGdFO and 3564 Oe belonging to NC sample that was obtained by sol-gel route having the 3:1 ratio. Squareness ratio (SQRs = Mr/MS) of NC sample (sol-gel, 4:1 ratio) is 0.371 as maximum and other samples have much lower values until a minimum of 0.121 (laser, 3:1) assign the multi-domain wall structure for all samples at 300 K. At 10 K data, just CNGaGdFO has 0.495 SQR value assigning single domain nature. The maximum values of effective crystal anisotropy constant (Keff) are 5.92 × 104 Erg/g and 2.4 × 105 Erg/g belonging to CNGaGdFO at 300 K and 10 K, respectively. Further, this sample has an internal anisotropy field Ha of 1953 Oe as largest at 300 K. At 10 K another sample (sol-gel, 3:1 ratio) has Ha,max of 11138 Oe which can also be classified as a soft magnetic material similar to other samples. Briefly, most magnetic parameters of NCs that were synthesized by sol-gel route are stronger than magnetic parameters of the NCs that were synthesized by PLAL at both temperatures. Some NC samples were observed to have stronger magnetic data as compared to magnetic parameters of Co0.5Ni0.5Ga0.01Gd0.01Fe1.98O4 NPs at 10 K.

“…[32] However, the biological and biomedical applications of silica-supported magnesium ferrite nanoparticles have received a lot of interest due to their anticancer and antibacterial properties. [33][34][35][36] They are widely used to control bacterial pollution and ultimately control many infections. [37] They are observed in many forms, such as thin films, [38] Nanopowders, [35] nanofibers, [39] nanowires, [40] nanospheres, even histoarchitecture geometry particles [41] and cubic spinel-type of structures also.…”

A novel, well‐designed, silica‐supported magnesium ferrite nanorods were successfully developed at room temperature using the co‐precipitation method. The synthesized nanorods show an optical band gap of 3.1 eV, with the maximum wavelength absorptive at 334 nm. The average particle size is 36 nm with the FCC crystal structure by the X‐ray Diffraction technique (XRD). TGA achieved thermal stability of targeted mesoporous materials at 600°C. Field Emission Scanning Electron Microscopy (FE‐SEM) and High‐Resolution Transmission Electron Microscopy (HR‐TEM) techniques confirm the rod‐like structure. Energy Dispersive Spectroscopy (EDS) and X‐Ray Fluorescence (XRF) studies reveal the presence of all elements in the composition. The synthesized nanorods are highly magnetic by the vibrating sample magnetometer (VSM) technique, which shows a high coercivity value, that is, MgFe2O4@SiO2 is photocatalytically active. From BET analysis, the surface area, pore volume, and pore diameter are 19.2 m2 g−1, 2.46 cm3 g−1, and 5.10 nm, respectively. The experimental outcomes predict that the degradation efficiency (79%) of methyl orange dye was accomplished using MgFe2O4SiO2 nanorods within 270 min.
