“…Close attention to these compounds appeared due to the interconnection of structural, charge, and spin interactions [7]. Multiferroics are the most relevant for research in the physics and chemistry of condensed matter [8][9][10]. Ferrites stand out among the most promising multiferroics [11][12][13].…”

Tm-Tb co-substituted Co-Ni nanospinel ferrites (NSFs) as (Co0.5Ni0.5) [TmxTbxFe2−2x]O4 (x = 0.00–0.05) NSFs were attained via the ultrasound irradiation technique. The phase identification and morphologies of the NSFs were explored using X-rays diffraction (XRD), selected area electron diffraction (SAED), and transmission and scanning electronic microscopes (TEM and SEM). The magnetization measurements against the applied magnetic field (M-H) were made at 300 and 10 K with a vibrating sample magnetometer (VSM). The various prepared nanoparticles revealed a ferrimagnetic character at both 300 and 10 K. The saturation magnetization (Ms), the remanence (Mr), and magneton number (nB) were found to decrease upon the Tb-Tm substitution effect. On the other hand, the coercivity (Hc) was found to diminish with increasing x up to 0.03 and then begins to increase with further rising Tb-Tm content. The Hc values are in the range of 346.7–441.7 Oe at 300 K to 4044.4–5378.7 Oe at 10 K. The variations in magnetic parameters were described based on redistribution of cations, crystallites and/or grains size, canting effects, surface spins effects, super-exchange interaction strength, etc. The observed magnetic results indicated that the synthesized (Co0.5Ni0.5)[TmxTbxFe2−x]O4 NSFs could be considered as promising candidates to be used for room temperature magnetic applications and magnetic recording media.

“…[54][55][56][57][58] Due to their improved magnetic properties, ordered magnetic materials such as nanorods and nanowires have recently drawn a lot of interest. 59,60 Other nanostructured forms of Mg-ferrite have not yet been identified, and the majority of the Mg-ferrite nanostructures that have been published so far are nano-composites. [61][62][63][64][65][66][67][68][69][70][71][72] An appealing quality that may be obtained from the nano fiberization of magnetic materials is a high surface-to-volume ratio.…”

This study focuses on the characterization and synthesis of ceramic materials that have magnetic nanoparticles (MgFe2O4) within an insulating (wüstite or magnesiowüstite) matrix (Mg1-xFexO). Ceramic Oxides were employed to absorb and elute rare-earth elements (REEs). Elements were carried out in experimental batches, including the effect of pH, adsorbent dose initial REE ions concentration, and equilibrium time. The Langmuir isotherm with a monolayer adsorption capacity surpassed 397 mg g−1 at room temperature. REE ions were effectively eluted from loaded Ceramic Oxides nanoparticles with 0.1 mol l−1 of HCl acid with an efficiency of 98%. Equilibrium modeling presented the Freundlich isotherm as the best fit model for both adsorbents and metal ions, indicating heterogeneity of the surface binding sites during adsorption. The pseudo-first order kinetic model was the best-fit model. Different qualitative techniques are used to emphasis the adsorption of REE ions onto Ceramic Oxides nanoparticles. The effect of REEs ions adsorption on the structural and morphological properties have been investigated using X-ray diffraction (XRD), porosity & surface area scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). The functional groups were detected by Fourier Transform infrared spectroscopy (FTIR). By applying a magnetic field of ±20 kOe, using vibrating sample magnetometer (VSM), (M-H) hysteresis loops were formed. The difference in ionic radius and atomic weight of the REE ions is highly renovated to the fluctuations in crystallographic and magnetic parameters. Finally, Ceramic Oxides nanoparticles possessed good adsorption properties such as stability and reusability, which have potential application in wastewater treatment.
