Summary: The impact of doping with different cations on the properties of CoFe2O4 nanoparticles synthesized via sol-gel method and calcined at different temperatures was investigated. The study found that doping cations affect the structural, thermal, kinetics, morphological, surface, and magnetic properties of the nanoparticles. Calcination at low temperatures results in low crystallinity while high temperatures lead to well-crystallized ferrites together with crystalline phases of the silica matrix. The structural and magnetic parameters of the nanoparticles also depend on the doping ion and calcination temperature.

Summary: Monte Carlo simulation was used to study the structural properties of polymer blend nanofilms with coarse-grained polyethylene-like models. The results showed that the densities in the bulk region increased and the films became thinner with sharper surface profiles for homopolymer films with stronger interchain interaction. For polymer blend films, components with weaker interchain interaction migrated to the surface region, while others located near the center. Increasing interchain interaction resulted in a higher degree of anisotropic orientation and distortion in chain dimension and shape, especially at the surface region.

Summary: Monte Carlo simulations were used to study the early stage of ordered-structure formation in linear and ring polyethylene chains. The simulations revealed that both linear and ring chains can form an ordered structure, but it is more difficult for ring chains. Molecular and structural properties indicated an ordering process and the need for stretching in ring polymer alignment.

Summary: Silver-substituted cobalt ferrite (Ag0.02Co0.98Fe2O4) nanoparticles were sensitized through coprecipitation method. Increasing annealing temperature resulted in larger crystallite size and grain size. The redistribution of cations led to a perfect spinel structure. Higher annealing temperature led to increased saturation magnetization and coercive field. The antibacterial properties of Ag0.02Co0.98Fe2O4 were demonstrated through evaluation on S. aureus and E. coli, with the most significant effects observed at annealing temperature of 200 degrees C.

Summary: We study the time evolution of spin squeezing in the one-dimensional spin-1/2 XY model subject to a sudden quantum quench of a transverse magnetic field. By analyzing the exact results of the model, we find that a proper choice of protocol can create spin-squeezed nonequilibrium states from an unsqueezed state. We also observe a nonanalyticity in the long-time average of the spin-squeezing parameter when quenching to the equilibrium quantum critical point, indicating different redistribution of quantum fluctuations among the spin components in the ferro-and paramagnetic phases away from equilibrium.

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.
