Magnetic skyrmions emerge as promising quasiparticles for encoding information in next-generation spintronic devices. Their innate flexibility in shape is essential for the applications although they were often ideally treated as rigid particles. In this work, we investigated the voltage-controlled uniform strain mediated dynamics of deformed skyrmions in heterostructures with a flower-shaped magnetic nanostructure, using micromagnetic simulations. The simulated results revealed the possible states of isolated skyrmion nucleated in the nanostructure, which can be mutually switched by applying suitable in-plane strain pulses. In addition, it was found that the skyrmion motions are driven by the emerging internal forces and strain force, which originate from the asymmetric deformation of skyrmion structures. Furthermore, an analytical model of deformed skyrmions was proposed to interpret the dependences of internal forces and strain force on the asymmetric deformation of skyrmion, with some formulas derived for these forces in a semianalytical approach. Further calculations based on these formulas verified the forces appearing in the skyrmion motion, with the resulting forces showing consistence with the simulated data. This suggested that our semianalytical model successfully captures the main physics responsible for the motion of deformed skyrmion in the nanostructure. Our work extends the understanding of the mechanics emerging in deformed skyrmion and provides an effective approach for deterministic manipulation of deformed skyrmion motion via strain forces and internal forces, which may be instructive to the design of skyrmion-based spintronic devices.

Deep-Learning Recognition of Scanning Transmission Electron Microscopy: Quantifying and Mitigating the Influence of Gaussian Noises

Scanning transmission electron microscopy (STEM) is a powerful tool to reveal the morphologies and structures of materials, thereby attracting intensive interests from the scientific and industrial communities. The outstanding spatial (atomic level) and temporal (ms level) resolutions of the STEM techniques generate fruitful amounts of high-definition data, thereby enabling the high-volume and high-speed analysis of materials. On the other hand, processing of the big dataset generated by STEM is time-consuming and beyond the capability of human-based manual work, which urgently calls for computer-based automation. In this work, we present a deep-learning mask region-based neural network (Mask R-CNN) for the recognition of nanoparticles imaged by STEM, as well as generating the associated dimensional analysis. The Mask R-CNN model was tested on simulated STEM-HAADF results with different Gaussian noises, particle shapes and particle sizes, and the results indicated that Gaussian noise has determining influence on the accuracy of recognition. By applying Gaussian and Non-Local Means filters on the noise-containing STEM-HAADF results, the influences of noises are largely mitigated, and recognition accuracy is significantly improved. This filtering-recognition approach was further applied to experimental STEM-HAADF results, which yields satisfying accuracy compared with the traditional threshold methods. The deep-learning-based method developed in this work has great potentials in analysis of the complicated structures and large data generated by STEM-HAADF. © 2024, CC BY.

We observe a temperature-independent point B_c in the longitudinal resistance R_xx of a GaAs-based two-dimensional electron gas in the quantum Hall plateau-plateau transition. This allows us to revisit the spin-degenerate plateau-plateau transition and use the R_xx peak movement with respect to B_c at various temperatures T so as to calculate the critical exponent κ. We suggest that one measures the maximum of the derivative of Hall resistivity dρ_xy/dB ∼ T^−κ as well as the movement of R_xx at different temperatures, allowing one to measure κs using two independent methods. When the peak movement is so large that the resistance peak is no longer in the vicinity of B_c, a largely deviated κ =0.54±0.04 from the value (0.21±0.02 ) in some spin-degenerate system can be measured. © 2023 The Physical Society of the Republic of China (Taiwan)

Due to the abundance of multiple elements and high-temperature synthesis in bismuth-based layered Aurivillius multiferroics, and thus it is of great significance to suppress the formation of impurity phases by controlling Bi concentration and to regulate multiferroicity through rare earth ion doping. The Aurivillius Bi7(1+y)Fe2CoTi3O21 (0 ≤ y ≤ 0.1) ceramics were prepared by solid state reaction method. X-ray diffraction results indicated that the impurity phases can be well restrained at an optimal Bi excess addition value of y = 0.04. Subsequently, a series of Nd-substituted Bi(7-x)(1+4 %)NdxFe2CoTi3O21 (0 ≤ x ≤ 1) samples were fabricated and their structure, magnetic, ferroelectric and optical properties were systematically investigated. The structural collapse behavior of all samples was demonstrated and it changed from an originally-designed 6-layered structure to the coexistence of 4- and 5-layered phases. The introduction of Nd ions improved the compactness while impeded the growth of grain. In particular, the composition x = 0.5 possessed a good room-temperature multiferroic property with remnant magnetization Mr of 0.89emu/g and remnant polarization Pr of 4.5 μC/cm2. Furthermore, its ferromagnetic and ferroelectric transition temperature were determined to be about 698K and 1080K, respectively. The variation of magnetic and ferroelectric properties with Nd content was discussed in detail. Meanwhile, the largely reduced absorption edges with band gaps of ∼1.3eV and ∼2.2eV were obtained in all bulks. The present work is expected to provide an avenue to optimize the multiferroicity and bandgap of multi-layer Aurivillius compounds. © 2025 Elsevier Ltd and Techna Group S.r.l.

Imaging sensing holds a remarkable place in modern electronics and optoelectronics for the complementary metal-oxide-semiconductor integration of high-speed optical communications and photodetection with the merits of high-speed operation, cost-effectiveness, and noncomplex fabrication. The optimum quality of image sensing relies on noise, sensitivity, power consumption, voltage operation, and speed imaging to access and compete with the state-of-the-art image sensing devices in the industry. Many studies have been conducted to address these issues;however, performance has not yet been optimized and solutions are still in the works. In this review, we briefly provide information on recent advances in image sensing using nanostructured emerging materials through nanofabrication integration including the technology evolution on traditional and modern technology platforms, general mechanisms, classification, and actual applications as well as existing limitations. Finally, new challenges and perspectives for the future trends of image sensing and their possible solutions are also discussed.

Inhibiting the “shuttle effect” of soluble polysulfides and improving reaction kinetics are the key factors necessary for further exploration of high-performance Li-S batteries. Herein, an effective interface engineering strategy is reported, wherein nitriding of an Ni-based precursor is controlled to enhance Li-S cell regulation. The resulting in-situ formed NiO-Ni_(3)N heterostructure interface not only has a stronger polysulfide adsorption effect than that of monomeric NiO or Ni_(3)N but also has a faster Li ion diffusion ability than a simple physical mixture. More importantly, this approach couples the respective advantages of NiO and Ni_(3)N to reduce polarization and facilitate electron transfer during polysulfide reactions and synergistically catalyze polysulfide conversion. In addition, ultrafine nanoparticles are thought to effectively improve the use of additive materials. In summary, Li-S batteries based on this NiO-Ni_(3)N heterostructure have the features of long cycle stability, rapid charging-discharging, and good performance under high sulfur loading.
