Spin Splitting in Altermagnetic RuO2 Enables Field-free Spin-Orbit Torque Switching via Dominant Out-of-Plane Spin Polarization

作者： Li, Zhuoyi Zhang, Zhe Lu, Xianyang Xu, Yongbing National Key Laboratory of Spintronics Nanjing University Suzhou215163 China Jiangsu Provincial Key Laboratory of Advanced Photonic and Electronic Materials School of Electronic Science and Engineering Nanjing University Nanjing210093 China School of Integrated Circuits Nanjing University Suzhou215163 China School of Physics Engineering and Technology University of York YorkYO10 5DD United Kingdom

Researchers have recently identified a novel class of magnetism, termed "altermagnetism", which exhibits characteristics of both ferromagnetism and antiferromagnetism. Here, we report a groundbreaking discovery of efficient field-free spin-orbit torque (SOT) switching in a RuO2 (101)/Co/Pt/Co/Pt/Ta structure. Our results demonstrate that the spin current flows along the [100] axis, induced by the in-plane charge current, with the spin polarization direction aligned parallel to the Néel vector. These z-polarized spins generate an out-of-plane anti-damping torque, enabling deterministic switching of the Co/Pt layer without the necessity of an external magnetic field. The altermagnetic spin splitting effect (ASSE) in RuO2 promotes the generation of spin currents with pronounced anisotropic behavior, maximized when the charge current flows along the [010] direction. This unique capability yields the highest field-free switching ratio, maintaining stable SOT switching within an external field range of approximately 400 Oe. Notably, ASSE dominates the spin current, especially when the current is aligned with the [010] direction (θ = 90°). Here, the spin polarization component σZ creates a substantial field-like effective field, surpassing the damping-like field from σy . This highlights the crucial role of σZ in enhancing spin-torque efficiency and elucidating spin flow modulation mechanics in this crystalline context. Our study highlights the potential of RuO2 as a powerful spin current generator, paving the way for practical applications in spin-torque switching technologies and other cutting-edge spintronic devices.

Topological edge states are crucial for optical modulation, and the overlapping Brillouin zones in nested structures can effectively control multiband edge states. A nested photonic crystal framework can enhance the rotational freedom, providing additional functionalities. In this study, a multifunctional, tunable, innovative double-rotation C₄ nested photonic crystal structure was developed;it reached a higher degree of freedom via double independent rotations. These nested C₄ photonic crystal structures could expand the functional range of C₄ structure implementation. The multifunctional implementation of multienergy band transmissions, unidirectional transmissions, and wavelength division multiplexers containing nested C₄ structures were experimentally demonstrated. The experimental results agreed well with the simulated predictions. Thus, this study offers new insights and strategies to foster the advancement of topological photonics and radar communication devices. © 2024 The Author(s)

Computed Tomography (CT) is an imaging technique widely used in clinical diagnosis. However, high-attenuation metallic implants result in the obstruction of low-energy Xrays and further lead to metal artifacts in the reconstructed CT images. Deep supervised model-based metal artifact reduction(MAR) approaches are limited in clinical applications due to the difficulty in obtaining paired artifact-affected and artifactfree data. Furthermore, these model-based methods lack the consideration of data consistency in the sinogram-domain to perform exact metal trace inpainting. To address these challenges, we propose a Data-consistent unsupErVised diffusiOn model for meTal artifact rEDuction, called DEVOTED-Net. First, DEVOTED-Net leverages prior knowledge to guide the conditional diffusion model for fine-grained metal trace inpainting. Second, an unsupervised MAR framework is designed in the reverse process for the unknown metal traces restoration in the sinogram domain. Third, to further enhance the sinogram-domain data consistency, physics-based consistency constraint loss including conjugateray consistency loss and accumulation-ray consistency loss is designed. Extensive experiments are carried out to verify the performance of our algorithm on the publicly available dataset and clinical experimental dataset. This efficient, accurate, and reliable MAR approach holds great potential in clinics.

The development of gel electrophoresis-based biodetection assays for accurate analysis has been limited by their reliability and reproducibility due to many interfering factors. In this work, we proposed a ratiometric gel electrophoresis-based biosensing platform by employing catalytic hairpin assembly (CHA) process function as both signal output and signal amplification module. The self-ratiometric biosensor had the advantages in miniaturized instruments, lower cost and satisfying reproducibility. Moreover, dual isothermal amplifications for nucleic acid enable improved sensitivity. Two types of nucleic acids DNA and miRNA are chosen for demonstration. The developed strategy reaches a detection limit of 230 fM for HBV and 130 fM for miRNA, respectively. More interestingly, this developed assay also has the potential to enable portable detection by introducing smartphone camera for imaging. In virtue of these advantages, the proposed ratiometric gel electrophoresis strategy indeed provides a new paradigm for the design of accurate detection platform and might hold great potential for sensitive diagnosis. © 2023, The Authors.
