Summary: In this study, Co-substituted Ni-Zn ferrites were synthesized, and their structural and magnetic properties were investigated. The results showed that Co substitution led to an increase in crystallite size and lattice constant, as well as a suppression of Raman peak intensity and shift towards a lower wavenumber. The dielectric properties and magnetic response of the samples were also affected by Co substitution. At low temperatures, the Co-substituted ferrites exhibited a giant coercivity and high effective magnetocrystalline anisotropy.

Summary: Nickel-zinc ferrite powders were prepared through conventional solid-state route and sintered at 1100 and 1300 degrees C for electromagnetic wave absorption. The samples sintered at 1300 degrees C showed high magnetic saturation and low coercivity, leading to high reflection losses at certain frequencies in the 3D contour plot. The microwave absorption performance was attributed to dielectric and magnetic loss mechanisms, with magnetic part prevailing.

Summary: The manufacturing and characterization of polymer nanocomposites is an active research trend, but statistical studies in this field are challenging due to various considerations. In this study, experimental characterization was conducted on two brands of FSRs to measure sensitivity, hysteresis error, and drift error. The results showed that lower mean values in error metrics are generally associated with higher dispersion, while higher mean values result in lower dispersion.

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.
