Magnetite nanoparticles (MNPs) are constantly studied in various biomedical applications, including magnetically-induced hyperthermia. This study tested the role of the dextran decomposition process on the MNPs crystallization and magnetic hyperthermia effect. It was confirmed that the modification of the synthesis method (medium and the procedure of the dextran introduction) results in the synthesis of magnetite nanoparticles with an average crystallite size from 3.88 ± 1.38 to 45.97 ± 0.76 nm and different magnetic properties. It was possible to synthesize nanoparticles with superparamagnetic properties (magnetization of 54.26 emu g⁻¹ and coercivity of 0.36 Oe) as well as a sample with a higher coercivity equal to 19.26 Oe and magnetization equal to 51.35 emu g⁻¹. The changes in the structure, morphology, and magnetic properties reflect the applicability potential of the magnetite nanoparticles in magnetic hyperthermia. The highest effect was observed for the sample synthesized in benzyl ether in the presence of dextran 40 000. For a concentration of 0.25 mg ml⁻¹, the specific absorption rate (SAR) was even higher than 200 W g⁻¹. However, as shown, the SAR parameter is insufficient to analyze the applicability potential, and the temperature increase must be consequently analyzed. For a concentration of 0.25 mg ml⁻¹, the temperature change was equal to 8.83 ± 1.03℃, while for 2 mg ml⁻¹ to 21.20 ± 0.83 ℃.

Magnetic spin textures, such as domain walls, skyrmions, and hopfions, exhibit dynamic properties that are essential for spintronic devices. A powerful method for understanding their normal modes and spin excitations is the eigenvalue approach, which relies on linearizing the Landau–Lifshitz–Gilbert equation. However, the nonuniform magnetization and nonlinear energy terms greatly increase the complexity of this linearization process, preventing eigenvalue-based methods from becoming standard in modern micromagnetic simulation tools. In this work, we present two novel approaches to implement the eigenvalue method: standard automatic differentiation (AD) and symbolic dual numbers. Both methods are integrated into the micromagnetic simulation package MicroMagnetic.jl. These approaches unify the treatment of linear and nonlinear terms, eliminating the need for manual derivations and enabling scalable, accurate analyses of excitation modes in both micromagnetic and atomistic models.

磁性自旋纹理（如畴壁、skyrmions 和 hopfions）表现出的动态特性对自旋电子器件至关重要。了解它们的法向模式和自旋激发的有力方法是特征值方法，该方法依赖于线性化 Landau-Lifshitz-Gilbert 方程。然而，非均匀磁化和非线性能量项大大增加了线性化过程的复杂性，使得基于特征值的方法无法成为现代微磁仿真工具的标准。在这项工作中，我们提出了实现特征值方法的两种新方法：标准自动微分（AD）和符号二元数。这两种方法都集成到了微磁仿真软件包 MicroMagnetic.jl。这些方法统一了线性和非线性项的处理，无需手动推导，可对微磁和原子模型中的激励模式进行可扩展的精确分析。

We report a theoretical study of the phase diagram of a ferrimagnetic iron-garnet with uniaxial anisotropy near a magnetization compensation point in the presence of a two-component magnetic field. The study is performed based on a quasi-antiferromagnetic approximation. The number and stability of the equilibrium states of the Neel vector are analyzed using the effective energy function. It is shown that application of the small out-of-plane magnetic field in addition to the stronger in-plane magnetic field significantly changes the equilibrium states of a ferrimagnet. The possibilities to control the equilibrium Neel vector position and to switch between the monostable and bistable states by tuning the value and ratio of the in-plane and out-of-plane magnetic field components are demonstrated. This opens new possibilities for the utilization of ferrimagnets since the magnetic field could be changed much faster than the temperature.

The Ising model is a central tool in the study of spin systems, with various generalizations to describe complex magnetic orderings. This work proposes a new application of the effective field theory (EFT) using clusters with

n

-sites, extending previous approaches to ferrimagnetic and antiferromagnetic states. Two specific cases are analyzed: a three-layer system of triangular lattices for ferrimagnetism and a square lattice for antiferromagnetism. The results include magnetizations, magnetic susceptibilities, and phase diagrams, showing that increasing the number of sites in the cluster improves accuracy, bringing the values closer to those obtained from Monte Carlo simulations. The proposed approach offers an efficient tool to study magnetic systems with different couplings and structural configurations. Although the new method presents improvements in numerical results, it is important to emphasize that its main contribution lies in introducing a more efficient approach, with simplifications in mathematical expansions aimed at reducing the computational time required in studies of this nature.

Electromechanical control of spin-Seebeck effects in armchair graphene nanoribbons

IF 2.5 3区材料科学 Q3 MATERIALS SCIENCE, MULTIDISCIPLINARY

This study investigates the electronic and thermoelectric properties of a periodic structure of twisted armchair graphene nanoribbons (TAGNRs). We consider three different widths for TAGNRs based on N dimer chains (N=3p+q, where q=mod (N,3)) with and without vacancy defects. In ideal TAGNRs, by increasing the torsion coefficient, the bandgap decreases for q=1 and significantly increases for q=2 and q=0 in the low torsion regime, similar to local twists in these structures. When introducing vacancy defects, the mean field Hubbard model predicts a spin-semiconducting effect in all classes of TAGNRs. A giant spin Seebeck coefficient (SSC) is observed with a large bandgap in defected TAGNRs by tuning the twisting effect and the width of the nanoribbon. Generally, the SSC value and spin currents strongly depend on the torsion coefficient, the location of vacancy defects, and the width of the nanoribbon. Finally, the electromechanical behavior of AGNRs can manipulate the thermoelectric properties especially the SSC in the presence of vacancy defects.

Spintronics is an emerging field that uses electronic spins for a variety of technical motivations. In this work, we used density functional theory (DFT) to investigate the ferromagnetic properties of

double-perovskite materials. We determined that the ferromagnetic indicate had the lowest level of energy in our recherche for the most ground-like configuration. We conducted stability tests and found that

exhibits thermodynamiclly, dynamically, and mechanically stability. They demonstrated the half-metallic ferromagnetic character of

B a_{2} S m O s O_{6}

through their band structure and density of states. These double-perovskites show potential for use in spintronic applications, as evidenced by their good magnetic moment values and spin polarisation factor. According to the studies, both materials have the ability to transmit at low energy, which makes them viable options for optoelectronic uses. Additionally, the discovery of discrete peaks for reflectivity and absorption signifies potential uses in flexible optical systems and sensors. Novel photonic material development is made possible by the refractive index’s dispersion properties.

A sinusoidal magnetization distribution as an original way to generate a versatile magnonic crystal for magnon propagation

The manipulation of the magnetization in a film at the nanoscale is one of the best means for controlling spin-wave propagation in real time. In 3D Magnonics, the vertical or interfacial interaction with patterned layers can make the film magnetization depart from uniformity, which, in general, can introduce new spin-wave modes in the film, hence additional degrees of freedom for signal manipulation. In this paper, we suggest a sinusoidal distribution for the magnetization as an original and effective way to generate a magnonic crystal and control its magnon dynamics. Along with a uniform bias field, we introduce in the film layer a sinusoidal bias field, simulating the vertical/interfacial interaction with other layers: after relaxation, the film magnetization assumes a sinusoidal equilibrium distribution. Using micromagnetic simulations followed by Fourier analysis, we show how to control the magnon dynamics by tuning the magnetization undulation amplitude and symmetry. We compute the magnon dispersion curves and space profiles, we show the occurrence of new degrees of freedom for signal manipulation and the rise of localized and stationary magnon modes. We highlight the physical mechanisms governing the occurrence and variation of the frequency-gap at zone-boundary. Finally, we indicate how to practically implement a sinusoidal field (and consequent magnetization) when the vertical coupling is the inverse magnetoelastic interaction between ferroelectric and ferromagnetic films. Our results suggest a new mechanism for controlling magnon propagation, which appears extremely appealing for its really wide range of tunable effects on their dynamics, particularly interesting in the engineering of signal filtering, information storage and delivery, and sensing activity.

This work investigates the metamagnetic transitions observed in the R₂RhIn₈ (R = Nd, Tb, Dy, Ho) series of compounds. These compounds crystallize in the tetragonal Ho₂CoGa₈-type structure with the P4/mmm space group. To replicate the metamagnetic transitions a four-sublattice Hamiltonian model which incorporates the crystalline electric field (CEF) interaction and the exchange interaction within the molecular field approximation is employed. The CEF parameters for Tb₂RhIn₈, Dy₂RhIn₈, and Ho₂RhIn₈ were determined by fitting and simulating their isothermal magnetization curves. The Nd₂RhIn₈ CEF parameters were taken from the literature. The exchange interaction parameters were adjusted to optimize the agreement between the model and experimental data. This four sublattice model effectively reproduces the low-field metamagnetic transitions observed in the R₂RhIn₈ (R = Nd, Tb, Dy, Ho) series of compounds.

We investigate the possibility of a square skyrmion crystal at a zero magnetic field by focusing on the mutual interplay among the charge, spin, and orbital degrees of freedom in electrons. By taking into account the effect of the spin–orbital coupling as the Dzyaloshinskii–Moriya interaction and that of the spin–charge coupling as the biquadratic interaction in an effective spin model and performing the simulated annealing, we find that the square skyrmion crystal is robustly stabilized from zero to finite magnetic fields on a two-dimensional noncentrosymmetric square lattice. We also show that the zero-field square skyrmion crystal changes into a topologically trivial double-
