Summary: In this study, CoNdxFe(2-x)O4 (x = 0.0-0.05) spinel ferrites were successfully synthesized through mechanical milling using solid-state reaction. The effects of Nd3+ ions on the structural, microstructural, magnetic, and microwave-absorbing properties of the samples were analyzed. It was found that the insertion of Nd3+ ions not only affected the magnetic parameters, but also played an important role in tuning the microwave absorption performance. The results suggest that Nd3+ ion-doped cobalt ferrite has potential for designing novel microwave-absorbing materials.

Summary: Research on tuning the magnetic properties of divalent ferrite materials has its own significance due to their wide applications in modern electronic and magnetic devices. This study focuses on the sono-chemical synthesis and characterization of pure and Sn doped CoFe2O4 nanoparticles (NPs). The obtained results reveal a stable cubic crystallographic structure, stable hard ferromagnetic state, and higher coercivity in Sn doped CoFe2O4 NPs compared to pure CoFe2O4. These findings suggest the potential application of Sn doped CoFe2O4 NPs in magnetic data storage.

Summary: In this study, a novel microwave-assisted method was developed to synthesize high-entropy oxide (HEO) nanoparticles. By varying the composition (Cr0.2Fe0.2Mn0.2Co0.2-xNi0.2Znx)3O4 (x = 0, 0.05, 0.1, and 0.2), nanoparticles with uniform distribution of metallic elements and particle sizes ranging from 10 to 50 nm were obtained. The suggested methodology is an excellent synthesis method due to its advantages of ultrafast, low-temperature fabrication of nanoscale and high-purity products at a relatively low cost.

Summary: Rare earth Pr3+ ion substituted spinel ferrite was prepared using sol-gel route. X-ray diffraction analysis confirmed the single phase composition of the samples with lower concentrations of Pr3+, but a secondary phase was observed in samples with higher Pr3+ concentrations. Fourier transform infrared spectra confirmed the formation of spinel ferrite. Field emission scanning electron microscopy revealed porous morphology and non-uniform grain growth in the samples. Vibrating sample magnetometer studies showed ferromagnetic behavior, with the coercivity increasing and then decreasing with increasing Pr3+ concentration. These synthesized spinel ferrites are suitable for supercapacitor electrode material due to their large surface area, presence of pore size, and soft magnetic nature.

Summary: The study compared superparamagnetic uncoated and silica-coated NiFe2O4@SiO2 nanoparticles with identical NiFe2O4 cores and found that the silica coating thickness significantly reduced the total magnetic anisotropy, allowing surface effects to manifest in the Mossbauer spectra. Additionally, Mossbauer spectra confirmed that reduced magnetization in uncoated NiFe2O4 nanoparticles was due to spin disorder, while silica coating enhanced spin canting on the NiFe2O4 surface.

Summary: The electrical and dielectric properties of Gd-substituted Sr hexaferrites were studied, showing that ac conductivity mainly depends on Gd3+ ion substitution ratios. Impedance analysis revealed that conduction mechanisms were mainly attributed to grain-grain boundaries in the NHFs. The dielectric constant of SrGdxFe12-xO19 NHFs exhibited a normal dielectric distribution with frequency due to varying substitution ratios.

Summary: Microspheres of Ni0.5Co0.5GaxFe2-xO4 (x≤1.0) spinel ferrites (NiCoGaFe-MSFs) and carbon spheres were synthesized via a hydrothermal technique. The microstructure of the microspheres was characterized using SEM, TEM, and XRD. The electrical and dielectric properties of NiCoGaFe-MSF were systematically studied at temperatures ranging from 20 to 120 degrees C (293.1 x 103 to 393.1 x 103) and frequencies up to 3.0 MHz. The results showed that the conductivity, dielectric properties, and impedance spectra of NiCoGaFe-MSFs were influenced by the Ga ion substitution ratios. The formation of semicircles in the impedance spectra was temperature-dependent, indicating a relaxation mechanism. The findings provide valuable insights for the design and application of spinel ferrite-based materials.
