Summary: In this study, the effects of adding nano-LiZn ferrite and V2O5 particles to LiZnTi ferrite were investigated. The addition of nano-LiZn led to a change in the microstructure, with the grains becoming more uniform and dense. The saturation magnetization (Ms) increased with increasing LiZn content and the addition of 4.0 wt.% nano-LiZn and 0.60 wt.% V2O5 resulted in improved magnetic properties.

Summary: Two groups of low-temperature-fired Ni0.6-xZn0.4CuxFe1.98O4 samples with different Bi2O3 doping levels were studied for their crystal phase composition, microstructure, and soft magnetic properties. Group A samples showed better overall performance than Group B samples, but were more sensitive to the Cu content. Therefore, for better performance, samples with x = 0.275 in Group A were recommended, while samples with x = 0.25 in Group B were more suitable for improved robustness of ferrite composition and process.

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.
