Summary: Hard ferrite (CoFe2O4), soft ferrite (Ni0.8Zn0.2Fe2O4), and composite ferrite (CoFe2O4)x/(Ni0.8Zn0.2Fe2O4)1-x (hard/soft ferrite) with varying compositions were synthesized by sol-gel auto combustion method. X-Ray Diffraction analysis confirmed the formation of cubic structures in the samples. Thermal analysis using TGA/DSC determined the temperature of phase formation. FTIR spectroscopy data verified the successful synthesis and formation of functional groups in the ferrites. SEM characterization showed overlapping spherical particles, and elemental mapping was performed using EDS. FESEM and TEM analysis demonstrated enhanced magnetic hyperthermia properties. Vibrating Sample Magnetometry was used to study the saturation magnetization (Ms), coercivity (Hc), and remnant magnetization (Mr) of the samples. Zeta potential measurement examined the surface charge of the particles in DI water. Heating characteristics of the samples were evaluated in an alternating magnetic field. The magnetic properties depended on the concentration of soft and hard ferrite, and the magnetic heating efficiency depended on the sample composition.

Summary: Hybrid improper ferroelectric Ca3Ti2O7 and Ca3Ti19Ru0.1O7 ceramics were successfully synthesized using the conventional solid-state reaction method. The Ru substitution led to changes in the crystal structure, decreased coercive field, and a lower optical bandgap due to impurity energy levels, as supported by first-principles calculations. The unexpected induced magnetic moments in Ru-doped Ca3Ti2O7 are also discussed.

Summary: The aim of this study was to create ZnO-NiO-Mn2O3 nanocomposites with improved physical and magnetic properties compared to individual oxides. The pure oxides ZnO, NiO, and Mn2O3 nanoparticles were synthesized and then ball milled to form four different nanocomposites. XRD analysis confirmed the crystal structures of the pure oxides and revealed the formation of spinel oxides in the nanocomposites. TEM analysis showed the versatile morphology of the nanoparticles in the nanocomposites. Elemental composition was confirmed by energy-dispersive X-ray analysis, and Raman analysis identified symmetry bands corresponding to the formation of tetragonal ZnMn2O4. DC-conductivity and VSM analysis showed the electrical and magnetic properties of the nanocomposites. The nanocomposite C4 exhibited the highest ferromagnetic nature. The photodegradation efficiency of the nanocomposite C1 towards Rhodamine B was also tested and showed the highest percentage of degradation.

Summary: We have investigated the dynamic magnetic properties of Ni-coated carbon fibers embedded in a polymer matrix for electromagnetic interference shielding applications. These hollow magnetic cylinders demonstrate unique dynamic magnetic characteristics, which were measured using a broad-band ferromagnetic resonance system. We observed three groups of FMR modes associated with different physical locations within the cylinders. An analytic model was developed to explain the results and micromagnetic simulations were conducted to verify the resonant mode profiles. The experimental results were found to be in excellent agreement with the theoretical models. Our study suggests that the global demagnetizing factors are not suitable for understanding the spin motions in these hollow cylinders and the FMR absorption observed in these cylinders differs significantly from that observed in nanowires or solid cylinders. The broad field-swept envelope of the FMR resonances can be important for electromagnetic shielding applications.

Summary: This study presents a silicon dielectric metamaterial (SDM) composed of two outer symmetric semi-circular rings and two inner symmetric split-ring resonators (SRRs). The electromagnetic responses of the SDM device in different modes were studied through numerical simulations and experiments. Increasing the structure height of the SDM device resulted in red-shifted resonances and stronger intensities. This study provides a new design strategy for the development of frequency filtering, polarization switching, and resonance modulation characteristics in THz-wave applications.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
