Summary: This study investigates the agglomeration of ferromagnetic nanoparticles in a fluid, highlighting the importance of interactions between ligand coatings in determining the shapes of agglomerates. Results show that particle clumping significantly affects their macroscopic properties, with important consequences for applications. In particular, the relationship between the work done by an oscillating field on the system and the sticking parameter c is nonmonotonic.

Summary: This study successfully fabricated high quality monocrystallite magnetite (Fe3O4) nanorings through a wet and mild-temperature-mediated chemical route, as an alternative to traditional solid-solid annealing methods. It also attempted to fabricate ferrite-based nanorings with different stoichiometry through metal-ion doping and solid-solid reaction by annealing hematite nanorings. The nanoring morphology was confirmed by electron microscopy, and magnetic vortex signature was observed in magnetic hysteresis cycle measurements.

Summary: In this study, the dynamics of chain formation in magnetic nanoparticles under applied magnetic fields were probed using time-resolved high-frequency hysteresis loops. The formation time of chains was found to strongly depend on the magnetic field amplitude, but not on the frequency studied. Both heating power and hysteresis loop squareness increase with time as chains form.

Summary: Combining tumor immunotherapy with nanoparticle-based hyperthermia has been found to enhance cancer treatment effectiveness. Tumor immunotherapy activates the immune system to attack cancer cells, while nanoparticle-based hyperthermia selectively kills cells by raising the temperature of tumor cells. The combination of both approaches can amplify anti-tumor responses, improve outcomes, and reduce side effects.

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.
