Summary: This paper investigates the effect of phase transformation on the mechanical and magnetic properties in multi-phase systems, using the AlCoCrFeNi high-entropy alloy as a candidate. Changes in volume fractions of different phases have divergent effects on mechanical and magnetic properties, with the formation of FCC phase positively affecting mechanical properties and the volume fraction of BCC phase playing a major role in determining magnetic properties.

Summary: The study investigates the FCC to BCC/B2 phase transformation in AlCoCrFeNi HEA, revealing that increasing heat treatment temperature and duration leads to increased yield strength and saturation magnetization but decreased fracture strain. Optimizing the transformation and size of B2 phases can achieve an excellent combination of mechanical and magnetic properties.

Summary: In this study, the mechanical properties and deformation mechanisms of CoCrFeNiMnx high entropy alloys (HEAs) were investigated through molecular dynamics (MD) simulation. Uniaxial tensile tests were conducted at different temperatures and manganese compositions, and a circular defect was created to study the damage tolerance of these HEAs. The results showed that the CoCrFeNiMn HEA exhibited a strong temperature dependence, with the ultimate tensile strength decreasing as the temperature increased. The early stage deformation was dominated by dislocation slip, while grain boundary glide played a major role in the later stage deformation. The higher manganese content led to the formation of hexagonal close-packed (HCP) and amorphous phases, which reduced the strength of CoCrFeNiMnx HEAs. Among the compositions tested, Mn5 HEA showed the best damage tolerance.

Summary: The influence of Si addition on the microstructure and magnetic properties of (FeCoNi)75Cu25-xSix (x = 0, 5, 10, 15, 20, 25 at. %) alloys synthesized by mechanical alloying was studied. Various characterization techniques were used to evaluate the phases and distribution of elements in the alloys. The alloys exhibited semi-soft magnet behavior, with the coercivity increasing significantly with an increase in Si content, while the saturation magnetization slightly fluctuated and then sharply declined with increasing Si content from 20 at. % to 25 at. %.

Summary: In this paper, a novel Fe49.85Cr10.03Mn10.03Co10.03Ni10.03Al10.03 high entropy alloy with dual-phase fine grain structure was designed and fabricated by arc-melting. The microstructure, as well as the mechanical properties at room temperature and cryogenic temperature, were investigated. The results showed that the as cast Fe-based HEA consisted of FCC and BCC phases, and the stick-like FCC fine grains were derived from solid-state phase transformation of BCC phase during cooling. Additionally, the alloy exhibited similar tensile strength and good plasticity at both room temperature and cryogenic temperature, indicating high mechanical properties over a wide range of temperatures. This work provides a novel route for designing high-performance fine-grain HEAs without mechanical/heat treatment and contributes to the further development of HEAs.

Summary: In this study, (NbTaMoW)Nx films were fabricated through reactive co-sputtering and their phase structures, mechanical properties, and corrosion resistance properties were investigated. The results showed that the stoichiometric ratio x of the films increased with increasing nitrogen flow ratios, leading to a transformation from body-centered cubic metal phases to face-centered cubic covalent nitride phases. The face-centered cubic phases were further classified into M2N-dominant and MN-dominant structures. The (NbTaMoW)Nx films prepared at specific nitrogen flow ratios demonstrated high hardness and Young's modulus values. The addition of nitrogen-containing films, including the (Nb0.16-Ta0.29Mo0.32W0.23)N0.07 film, improved the corrosion resistance of the substrate.

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.
