Summary: A phenomenon of Y3Fe5O12 (YIG)-ferromagnetic-resonance (FMR) linewidth broadening in magnetically coupled YIG-Co films is reported. The broadened linewidth is attributed to a new type of inhomogeneity effect induced by the inhomogeneous dipolar field of the Co layer. The extent of the linewidth broadening depends on the magnetization state of Co, and the influence of Co on YIG-FMR linewidth is a long-range effect due to the dipolar origin even when the spacer between YIG and Co is 315 nm.

Summary: This paper presents a theoretical work based on the second quantification of spin waves in ferromagnetic/non-magnetic multilayers. The aim of this theoretical approach is to model the excitation modes of spin waves at low temperature. The study investigates the effect of the characteristic parameters of the system on the spin wave dispersion modes. It is found that spin waves located at the interfaces play a crucial role in the stability/instability of the magnetic state in the multilayers, and that dipolar interactions, interface anisotropy, and exchange interactions have a significant influence on the energy of these modes.

Summary: In this paper, the dynamics properties of three-component antiferromagnetic dipolar Bose-Einstein condensates with external magnetic field are studied. Numerical simulations of the spinor Gross-Pitaevskii equation are employed to obtain the results. It is found that the population of the spin components is strongly influenced by magnetic field and the dynamical evolution process is accelerated. The study also reveals the emergence of periodic oscillation in spin exchange dynamics and the same amplitude of the components mf = ±1. Additionally, the influence of dipolar interaction is masked by the presence of magnetic field, as shown in the density profile. Moreover, an order parameter is introduced to characterize the disorder-order crossover, indicating that the system develops towards a disordered state with strong dipole strength when magnetic field is included.

Summary: The study demonstrates that the nanocrystal system coupled via dipolar interaction shows an anti-crossing behavior under an external applied magnetic field, resulting in a Lorentz-shaped photoluminance intensity signal with an unusual dip-shape at the zero detuned states. This dip-shape corresponds to the point where crossing would occur in the absence of dipolar interaction.

Summary: The effective magnetic anisotropy field Heff of Fex Ni(100-x) (x = 15, 25, 38) nanowires within dense alumina templates of-35% porosity was determined using different methods including magnetization evolution, ferromagnetic resonance, and magnetization switching. The results showed variations in Heff values depending on the determination method, with the values from magnetization measurements being quite smaller than those from FMR measurements. It was suggested that new internal degrees of freedom need to be considered to describe the effective anisotropy in different processes.

Summary: The tunable mechanical properties and magnetostriction of Magnetoactive (MA) foam have the potential for soft sensor technology development. However, researchers have found that its capabilities are morphologically dependent, and in this work, MA foam was developed with additional capabilities by manipulating the concentration of carbonyl iron particles (CIPs) and the magnetic field. The highly sensitive MA foam could potentially be implemented in future soft sensor systems.

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.
