Summary: In this study, low-power-loss Mn-Zn ferrite was prepared using traditional ceramic sintering process. The sample exhibited good wide-temperature stability of power loss. The effect of uniaxial compressive stress on power loss at different frequencies was investigated, and the mechanism behind the stress-induced power loss was clarified. The findings are beneficial for the development of new soft ferrite materials with low stress sensitivity for high-frequency applications.

Summary: Densified MnZn ferrite ceramics were prepared using the cold sintering process under pressure, with an acetate ethanol solution used as the transient solvent. The effects of the transient solvent, pressure, and annealing temperature on the density, micromorphology, and magnetic properties of the sintered MnZn ferrites were studied. The cold sintering process, along with the transient solvent and high pressure, is crucial for achieving densified MnZn ferrite. Additionally, the annealing treatment is necessary to increase the density further and reduce power loss at high frequencies.

Summary: The temperature dependence of complex permeability and power losses in Mn-Zn ferrite is investigated. The study reveals that the Hopkinson peak and domain-wall resonance peaks shift with temperature, and the transition of domain-wall resonance peaks from relaxation type to resonance type is related to the reduction of loss factor. Moreover, the power losses exhibit different temperature dependencies for different loss contributions.

Summary: In this study, MnZn ferrites with added YIG nanoparticles were developed for MHz frequency applications. It was found that a small amount of added YIG effectively reduces the power loss and increases the initial permeability of MnZn ferrites. The optimal MnZn ferrite with 600 ppm added YIG showed a significant reduction in power loss, an increase in initial permeability, and good stability against temperature.

Summary: Manganese-zinc ferrites are preferred for high-frequency and high-power magnetic components. However, manufacturers' material specifications lack sufficient information for design optimization. This article proposes a method to determine the properties of Mn-Zn ferrite and provides experimental frequency characteristics for four ferrite materials. The impacts of physical size, temperature, and force on ferrite properties are also considered.

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.
