Summary: Magnetic soft ferrites, namely manganese-zinc ferrite, nickel-zinc ferrite and their combinations, were incorporated into acrylonitrile-butadiene rubber with carbon fibers to fabricate composite materials. The effect of the fillers on absorption shielding performance of the composites within the frequency range 1-6 GHz was investigated. Results showed that the absorption shielding efficiency of both composites increased with increasing proportion of nickel-zinc ferrite. The addition of carbon fibers and ferrites resulted in lower absorption shielding performance due to their higher electrical conductivity and permittivity.

Summary: The contributions of dielectric and magnetic genes in a NiO/NiFe2O4/reduced graphene oxide heterostructure are dissected to realize tunable electromagnetic (EM) function. This manipulation leads to tunable microwave absorption performance and electromagnetic interference shielding performance, with the minimum reflection loss reaching -55.0 dB, matching thickness decreasing to 2.3 mm, effective absorption bandwidth increasing to 6.4 dB, and electromagnetic interference shielding effectiveness up to 8.69 dB. Furthermore, a self-powered EM energy conversion device is designed based on this manipulation, enabling the conversion of waste EM energy into electric energy and the recycling of EM energy. This study provides a theoretical basis for manipulating EM response and designing next-generation EM attenuation materials, contributing to the development of next-generation smart devices and environmental protection.

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.
