Аннотация: The phenomenon of shape anisotropy predominantly constitutes the principal factor influencing effective anisotropy, serving as a significant determinant of the magnetic characteristics of one-dimensional ferromagnetic nanostructures, materials that hold substantial promise for a diverse array of applications in the domains of electronics and biomedicine. However, it is noteworthy that effective anisotropy may be modulated through the manipulation of various other forms of anisotropy, thereby facilitating the tuning of the magnetic properties of nanowire arrays without necessitating alterations to their spatial curvature. In this study, we elucidate the characteristics of nanowire arrays with varying lengths and compositions, which have been electrochemically synthesized utilizing identical porous templates. Through a range of experimental methodologies, we establish a correlation between atypical magnetic behavior and the underlying morphology and crystalline structure of the nanowires. We attribute the pronounced magnetostatic interactions observed within cobalt (Co) nanowires to the presence of significant local uniaxial magnetocrystalline anisotropy, along with a nanostructure oriented perpendicular to the longitudinal axis of the nanowire. Furthermore, we examine the repercussions of substantial discrepancies in the lengths of iron (Fe) nanowires on the magnetostatic field distribution. Our analysis employs mean field theory, incorporating the contributions of various anisotropies present within the system, as well as the non-uniform lengths of the nanowires. Ultimately, through micromagnetic simulations, we investigated the stray fields present within the nanowire array and delineated how strong magnetocrystalline anisotropy and the variability in length affect their spatial distribution.

Laser-induced silver nanowires/polymer composites for flexible electronics and electromagnetic compatibility application / I. Bril’, A. Voronin, Yu.

flexible electronics -- silver nanowires -- sheet resistance -- shielding efficiency
Аннотация: Nowadays, the Internet of Things (IOT), electronics, and neural interfaces are becoming an integral part of our life. These technologies place unprecedentedly high demands on materials in terms of their mechanical and electrical properties. There are several strategies for forming conductive layers in such composites, e.g., volume blending to achieve a percolation threshold, inkjet printing, lithography, and laser processing. The latter is a low-cost, environmentally friendly, scalable way to produce composites. In our work, we synthesized AgNW and characterized them using Ultraviolet-visible spectroscopy (UV-vis), Transmission electron microscopy (TEM), and Selective area electron diffraction (SAED). We found that our AgNW absorbed in the UV-vis range of 345 to 410 nm. This is due to the plasmon resonance phenomenon of AgNW. Then, we applied the dispersion of AgNW on the surface of the polymer substrate, dried them and we got the films of AgNW. We irradiated these films with a 432 nm laser. As a result of the treatment, we observed two processes. The first one was the sintering and partial melting of nanowires under the influence of laser radiation, as a consequence of which, the sheet resistance dropped more than twice. The second was the melting of the polymer at the interface and the subsequent integration of AgNW into the substrate. This allowed us to improve the adhesion from 0–1 B to 5 B, and to obtain a composite capable of bending, with radius of 0.5 mm. We also evaluated the shielding efficiency of the obtained composites. The shielding efficiency for 500–600 nm thick porous film samples were 40 dB, and for 3.1–4.1 µm porous films the shielding efficiency was about 85–90 dB in a frequency range of 0.01–40 GHz. The data obtained by us are the basis for producing flexible electronic components based on AgNW/PET composite for various applications using laser processing methods.

Magnetization processes in two-dimensional arrays of iron nanowires / D. L. Zagorskiy, S. V. Semenov, S. V. Komogortsev [et al.] // J. Magn. Magn.

Nanowires -- Magnetic measurements -- Micromagnetic modeling
Аннотация: Arrays of iron nanowires (NWs) obtained by template-assisted electrodeposition constitute a promising composite material characterized by a combination of high magnetization in the filler and perpendicular magnetic anisotropy. The properties of these composites arise from the interplay between the behavior of individual NWs and their magnetostatic interactions. In this study, we investigated NW arrays with identical wire diameters but varying spatial arrangements. Major hysteresis loops were studied under various field directions relative to the NW axis. Key parameters such as the slope of the magnetization curve, saturation magnetization, and coercive force were quantified. Additionally, FORC (First Order Reversal Curve) measurements were conducted with the field oriented longitudinally with respect to the NW, offering insights into the inhomogeneity of the demagnetizing field influenced by the NW array's configuration. In the sample with the highest NW density, we observed isotropic behavior of the effective demagnetizing field, and we proposed an explanation for this phenomenon using the effective media approach. Micromagnetic simulations revealed that the magnetic behavior of individual NWs with a 100 nm diameter can be described as an interchange between volumes characterized by vortex and uniform magnetization patterns. Calculations of the demagnetizing field using the effective medium model demonstrated excellent agreement with experimental data across arrays featuring different NW densities. Remarkably, the quantitative consistency of coercive field values obtained from micromagnetic simulations and experimental measurements in the range of angles from 0° to 45° for the studied samples underscores the structural homogeneity of the obtained NWs.

Аннотация: A plasma-chemical method for the modification of silicon carbide particles is presented, which makes it possible to obtain particles with a controlled surface morphology. The variable parameter of particle processing was the ratio of the fraction of plasma-forming (Ar) and additional (H) gases. It was shown that at Ar/H = 100/0, the formation of a carbon shell is observed; at Ar/H ratios of 91/9 and 84/16, the particles are characterized by a carbon shell decorated with silicon nanoparticles or nanowires, respectively. The modified particles were analyzed using scanning electron microscopy and Raman spectroscopy.

superconducting nanowires -- Majorana zero modes -- strong electron correlations
Аннотация: For superconducting nanowire with the pairing of extended s-type symmetry, Rashba spin-orbit interaction in a magnetic field, the influence of strong intersite charge correlations on single-particle Majorana excitations is analyzed. This problem is investigated on the basis of the density matrix renormalization group numerical method. It is shown that with an increase in the repulsion intensity of electrons located at the neighboring sites, two subbands emerge in the lower Hubbard band of the open system. Based on calculations of the Majorana polarization and degeneracy of the entanglement spectrum, it was found that a topologically nontrivial phase with one edge state survives at the edge of each of the subbands where the concentration of electrons or holes is minimal.

Nanowires -- Statistical mechanics -- Topology
Аннотация: We analyze the behavior of caloric characteristics and the electron component of the spin polarization of excitations in the regime of strong electron correlations of a nanowire, which is characterized by induced superconductivity of the extended s-type symmetry, the Rashba spin–orbit interaction, and the Zeeman splitting of on-site energy. The problem has been analyzed using the density matrix renormalization group method. It is shown that for unambiguous identification of different phases (the topologically trivial phase with edge excitations and without them, as well as topologically nontrivial phases with one or several pairs of Majorana modes), it is insufficient to analyze each of the aforementioned characteristics separately; it is necessary to consider their features simultaneously.
