“…Manganese substitution of zinc in Mg-Zn ferrites enhances the superexchange relations involving tetrahedral (A) and octahedral (B) sites of the cubic lattice spinel ferrite structure [46]. Yang et al [47] explored the influence of substituting Zn with Mg in Zn-Co ferrites on the Curie temperature (Tc), magnetic properties, and heating efficiency, showing that a higher in Mg 2+ content results in Tc growth due to enhancement of the A-B super-exchange relations. Substitution of zinc with magnesium also increased the specific absorption rate (SAR), achieving a stable temperature of 44.7 °C for x = 0.3 in MgxZn0.8-xCo0.2Fe2O4.…”

Spinel ferrites are a widely investigated and applied class of materials with a cubic spinel lattice structure. Their unique multifunctional properties (magnetic characteristics, tunable shape/size, large number of active surface sites, high values of specific surface area, good chemical stability, and possibilities for enhancing properties through surface modification) influenced by the synthesis procedure make them attractive for biomedical applications as magnetic nanoparticles in drug delivery to a set target, magnetic hyperthermia, tissue engineering, magnetic extraction of biological components and magnetic diagnostics. In this review, we give an overview of up-to-date synthesis procedures for obtaining magnetic spinel nanoparticles and nanocomposites with optimal properties for biomedical applications.

In this article, we propose SNG (single negative) metamaterial fabricated on Mg–Zn ferrite-based flexible microwave composites. Firstly, the flexible composites are synthesized by the sol-gel method having four different molecular compositions of MgxZn(1−x)Fe2O4, which are denoted as Mg20, Mg40, Mg60, and Mg80. The structural, morphological, and microwave properties of the synthesized flexible composites are analyzed using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and conventional dielectric assessment kit (DAK) to justify their possible application as dielectric substrate at microwave frequency regime. Thus the average grain size is found from 20 to 24 nm, and the dielectric constants are 6.01, 5.10, 4.19, and 3.28, as well as loss tangents, are 0.002, 0.004, 0.006, and 0.008 for the prepared Mg–Zn ferrites, i.e., Mg20, Mg40, Mg60, and Mg80 respectively. Besides, the prepared low-cost Mg–Zn ferrite composites exhibit high flexibility and lightweight, which makes them a potential candidate as a metamaterial substrate. Furthermore, a single negative (SNG) metamaterial unit cell is fabricated on the prepared, flexible microwave composites, and their essential electromagnetic behaviors are observed. Very good effective medium ratios (EMR) vales are obtained from 14.65 to 18.47, which ensure the compactness of the fabricated prototypes with a physical dimension of 8 × 6.5 mm2. Also, the proposed materials have shown better performances comparing with conventional FR4 and RO4533 materials, and they have covered S-, C-, X-, Ku-, and K-band of microwave frequency region. Thus, the prepared, flexible SNG metamaterials on MgxZn(1−x)Fe2O4 composites are suitable for microwave and flexible technologies.
