Summary: Magnesium ferrite nanoparticles were synthesized using the solution combustion method. The effect of fuel concentration on the spectroscopic, structural, and magnetic properties of MgFe2O4 was investigated. The results showed that increasing the fuel amount led to a decrease in crystallite size and an increase in lattice strain, dislocation density, and specific surface area. The study also revealed that the number and parameters of magnetic sextets assigned to different sites varied slightly with different fuel concentrations.

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: CeFeO3 nanoparticles were synthesized by a fast microwave-thermal treatment method in the presence of PVP. The synthesized nanoparticles exhibited different crystallite sizes and weak ferromagnetic behavior. The optical band gap of the CeFeO3 nanoparticles decreased with the calcination temperature. Under visible light, the CeFeO3 nanoparticles showed good photocatalytic activity in the degradation of methylene blue, with higher activity observed at lower calcination temperatures. The CeFeO3/GO nanocomposite demonstrated excellent photocatalytic efficiency, making it a potential candidate for highly efficient degradation of organic dyes under visible light radiation.

Summary: The electronic structure and ferroelectric-ferromagnetic coupling properties of Y-doped and vacancy-containing GaN-ZnO heterojunctions are systematically investigated. The magnetism in vacancy-containing systems is generated by the spin polarization of unpaired electrons induced by cationic vacancies, while in Y-doped systems, bound magnetic polarons are formed by the orbital hybridization of s-state and d-state electrons of Y-doped elements.

Summary: The elementary excitations spectrum of anisotropic frustrated antiferromagnets in the fan phase is discussed. It is found that the low-energy part of the spectrum consists of a gapless phason branch with linear dispersion and a gapped optical branch corresponding to the fan structure amplitude oscillations. In the high-energy part of the spectrum, the excitations are similar to the magnons of the fully polarized phase.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
