“…-O absorption bands around 585 cm −1 corroborates that the main phase of as-prepared particles is magnetite[21][22][23][24][25]. Two characteristic bands at 2900-2800 cm −1 of C-H stretching and 1116-1050 cm −1 of C-O stretching in spectra confirm the attachment of TEG on the particle surfaces[26][27][28][29][30][31].…”

In this present study, a facile synthetic route was developed to prepare super-paramagnetic Fe 3 O 4 MNPs directly via a one-pot approach. In this synthesis, only one iron containing compound and instead of high-boiling-point solvents, water-soluble tetraethylene glycol (TEG) was used as both the solvent and surfactant to control the particle growth and to prevent the aggregation of particles. Crystallite, particle, and magnetic core size are in good agreement with each other. The VSM measurement shows the superparamagnetic property of the product. The existence of TEG layer on the surface of the Fe 3 O 4 nanoparticles was confirmed by Fourier transform infrared spectroscopy and thermal gravimetric analysis. The monodisperse morphology of the product was presented via TEM analysis. Due to the monodisperse morphology, superparamagnetic property, and small particle size, the product may have a potential application in biomedical research field.

“…These bands can be attributed to the stretching of the vibration band between F and O. The vibration bands shifted toward higher wavenumbers when the Nb 3+ content increased, which was due to the variation in the bond length as a result of the larger ionic radii of Nb 3+ [24,25,26].…”

Co0.5Ni0.5NbxFe2−xO4 (0.00 ≤ x ≤ 0.10) nanoparticles (NPs) were prepared using the hydrothermal approach. The X-ray powder diffraction (XRD) pattern confirmed the formation of single-phase spinel ferrite. The crystallite size was found to range from 18 to 26 nm. The lattice parameters were found to increase with greater Niobium ion (Nb3+) concentration, caused by the variance in the ionic radii between the Nb3+ and Fe3+. Fourier transform infrared analysis also proved the existence of the spinal ferrite phase. The percent diffuse reflectance (%DR) analysis showed that the value of the band gap increased with growing Nb3+ content. Scanning electron microscopy and transmission electron microscopy revealed the cubic morphology. The magnetization analyses at both room (300 K, RT) and low (10 K) temperatures exhibited their ferromagnetic nature. The results showed that the Nb3+ substitution affected the magnetization data. We found that Saturation magnetization (Ms), Remanence (Mr), and the Magnetic moment ( n B ) decreased with increasing Nb3+. The squareness ratio (SQR) values at RT were found to be smaller than 0.5, which postulate a single domain nature with uniaxial anisotropy for all produced ferrites. However, different samples exhibited SQRs within 0.70 to 0.85 at 10 K, which suggests a magnetic multi-domain with cubic anisotropy at a low temperature. The obtained magnetic results were investigated in detail in relation to the structural and microstructural properties.
