Summary: This study investigates the in-plane anisotropy of linear and nonlinear magnetoelectric effects in a heterostructure composed of amorphous iron-based ferromagnet and piezoelectric lead zirconate-titanate ceramics. The results show strong uniaxial or biaxial anisotropy for different directions of the bias field within the sample plane.

Summary: Anisotropic magnetoelectric (ME) effects are investigated in a planar multiferroic heterostructure consisting of a piezoelectric lead zirconate-titanate substrate and a grating of ferromagnetic Ni-strips electrodeposited on its surface. The magnitudes of both the linear and nonlinear ME effects depend on the orientation of the magnetic fields and the distance between the strips. The strong anisotropy of ME effects arises due to demagnetization in a single Ni-strip and dipole-dipole interaction between the adjacent strips. A calculation technique is proposed to describe the anisotropy of ME effects in the heterostructure.

Summary: Magnetoelectric multiferroics have attracted much attention due to their potential applications in novel multifunctional devices. Compared to single-phase multiferroics, magnetoelectric composites have competitive advantages, and their coupling is influenced by composition and grain size. In this study, BFO/PZT composites were prepared via solid-state sintering, and the equal molar ratio composition showed a better magnetoelectric coupling response. The composites with nano bismuth ferrite and both nano/micro grain sizes exhibited the highest magnetoelectric voltage coefficients (<< E = 16.9 mV cm-1 Oe-1). The strain-mediated mechanism was confirmed by comparing the strain response and polarization of nano/micro composites with a composition ratio of 3:7.

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.
