Summary: In this study, the effect of gamma-irradiation on the structural and AC electrical properties of Ni-Zn nanoparticles was investigated. XRD analysis showed a decrease in crystallite size with increasing Zn2+ ion concentration, and irradiation influenced the crystallite size. The lattice constant increased with Zn2+ concentration, but changes occurred after irradiation. Irradiation also affected the lattice strain and morphology of the samples. In terms of AC electrical properties, irradiation increased the dielectric constant but decreased the dielectric loss and AC conductivity, and the type of dielectric relaxation changed.

Summary: The dielectric properties of V2O5-added Ni-Co-Zn ferrites were investigated, showing a decrease in dielectric constant and increase in electrical resistivities. AC conductivity was reduced at lower frequencies but sharply increased at higher frequencies, possibly due to enhanced electron hopping between Fe2+ and Fe3+ ions. Impedance spectroscopy revealed conduction mechanism through grain/bulk property, attributed to the larger grain size of V2O5-added ferrites.

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.
