Polar nano-regions enable large spin Hall conductivity in metallic PtCoO 2
Abstract Spin-source materials for spintronic devices are required to convert charge currents into spin currents efficiently and maintain minimal electrical losses. However, conventional strategies to enhance charge–spin conversion often come at the cost of increasing ohmic dissipation. Here we demonstrate that introducing polar lattice distortions into a highly conductive metal can overcome this trade-off.
Unconventional magnon-mediated spin torque enabled by ferroelectric domain engineering in multiferroic BiFeO 3
Abstract Spin current provides an energy-efficient approach for manipulating magnetization, when its spin polarization aligns with the magnetization direction. However, conventional spin-source materials possess high crystalline symmetry, restricting spin polarization to be orthogonal to both spin and charge current directions.
Wave characteristics and wave energy resource assessment of the waters bordering China
Abstract Wave energy is a clean and renewable marine resource with great development potential. The China Sea, including the Bohai Sea, Yellow Sea, East China Sea and South China Sea, has complex marine conditions. This study aims to clarify the wave characteristics and spatiotemporal distribution of wave energy resources in the China Sea, providing a scientific basis for its rational development and utilization.

Antiferromagnetic quantum anomalous Hall effect under spin flips and flops - Nature
Abstract The interplay between nontrivial band topology and layered antiferromagnetism in MnBi2Te4 has opened a new avenue for exploring topological phases of matter1,2,3,4. The quantum anomalous Hall effect5 and axion insulator state6 have been observed in odd and even number layers of MnBi2Te4, and the quantum metric nonlinear Hall effect7,8 has been shown to exist in this topological antiferromagnet.
Significance in Numerical Simulation and Optimization Method Based on Multi-Indicator Sensitivity Analysis for Low Impact Development Practice Strategy
1. Introduction Traditional urban development focuses on high-intensive, hardened land utilization and can damage the natural water cycle, which significantly increases surface runoff and increases the urban waterlogging risk [1]. Sponge cities aim to protect the original ecological structures, including lakes, rivers, greenbelt, etc., to maintain the natural hydrological characteristics before urbanization [2].
Towards the quantized anomalous Hall effect in AlOx-capped MnBi2Te4 - Nature Communications
Abstract The quantum anomalous Hall effect in layered antiferromagnet MnBi2Te4 harbors a rich interplay between magnetism and topology, holding a significant promise for low-power electronic devices and topological antiferromagnetic spintronics. In recent years, MnBi2Te4 has garnered considerable attention as the only known material to exhibit the antiferromagnetic quantum anomalous Hall effect.

Voltage control of multiferroic magnon torque for reconfigurable logic-in-memory - Nature Communications
Abstract Magnons, bosonic quasiparticles carrying angular momentum, can flow through insulators for information transmission with minimal power dissipation. However, it remains challenging to develop a magnon-based logic due to the lack of efficient electrical manipulation of magnon transport. Here we show the electric excitation and control of multiferroic magnon modes in a spin-source/multiferroic/ferromagnet structure.
Acoustic-driven magnetic skyrmion motion - Nature Communications
Abstract Magnetic skyrmions have great potential for developing novel spintronic devices. The electrical manipulation of skyrmions has mainly relied on current-induced spin-orbit torques. Recently, it was suggested that the skyrmions could be more efficiently manipulated by surface acoustic waves (SAWs), an elastic wave that can couple with magnetic moment via the magnetoelastic effect.
Mobilization, Speciation, and Transformation of Organic and Inorganic Contaminants in Soil-Groundwater Ecosystems
The delicate balance of our ecosystems is under threat from the unrelenting release of contaminants into the environment. Among the most concerning are organic and inorganic pollutants that infiltrate the soil and permeate into the groundwater, posing significant risks to both environmental health and the wellbeing of humans who use groundwater as drinking water.
Field-free spin-orbit switching of perpendicular magnetization enabled by dislocation-induced in-plane symmetry breaking - Nature Communications
Abstract Current induced spin-orbit torque (SOT) holds great promise for next generation magnetic-memory technology. Field-free SOT switching of perpendicular magnetization requires the breaking of in-plane symmetry, which can be artificially introduced by external magnetic field, exchange coupling or device asymmetry. Recently it has been shown that the exploitation of inherent crystal symmetry offers a simple and potentially efficient route towards field-free switching.
Exploring the relationship between unemployment perception and health during COVID-19: a comparative study of rural and urban adults in China
Introduction The COVID-19 pandemic has been an ongoing global public health crisis, causing more than 600 million confirmed infection cases with over 6 million deaths worldwide (WHO, 2023). Governments have implemented various policies, including social distancing, isolations, travel restrictions, lockdowns, and masking mandates, to curtain the spread. The pandemic has seriously affected the world's economic and political conditions (Chen G. et al., 2022; Fang et al., 2022a,b).
Blowing magnetic skyrmion bubbles
Skyrmions are tiny whirlpools of magnetic spin with potential to act as carriers of information in future devices. Skyrmions have been observed in multiple materials but usually at impractically low temperatures. Jiang et al. used a constriction in a trilayer system to create skyrmions at room temperature (see the Perspective by von Bergmann). The authors pushed elongated magnetic domains through the constriction using an in-plane current, causing individual skyrmion bubbles to form.
