Magnetic and Crystal Symmetry Control on Spin Hall Conductivity in Altermagnets

open access: yesAdvanced Science, EarlyView.
Crystal structures and schematic illustrations of the spin Hall effect (SHE) in altermagnets. High‐symmetry RuO2 exhibits conventional SHE, while tilted RuO2 shows trivial unconventional SHE (USHE) caused by structural tilting. CrSb and MnTe, with reduced magnetic symmetry, display intrinsic USHE arising from symmetry‐driven spin–momentum locking ...

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion

open access: yesAdvanced Science, EarlyView.
In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

open access: yesAdvanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

Multi‐Dimensional Acoustic Cascaded Holographic Encryption with Instantaneous Visual Decryption via Particle Manipulation

open access: yesAdvanced Science, EarlyView.
Acoustic holograms act as key tools for information encryption, yet current schemes limit encryption dimensionality/security and require time‐consuming decryption. A compact device integrates multi‐dimensional cascaded acoustic holography with particle manipulation, employs extra secret keys, enables rapid decryption, and is validated via 1D/2D/3D ...

POSS Polyimide Composite Sealed Triple‐Junction GaAs Thin‐Film Solar Cell for Long‐Term Low Earth Orbit Serve

open access: yesAdvanced Science, EarlyView.
Ultrathin oxide layer and ultraviolet absorbent are introduced into polyhedral oligomeric silsesquioxane (POSS) polyimide to improve the transmittance conservation and realize near zero mass loss against ultraviolet and atomic oxygen exposures. The POSS polyimide composite sealed triple‐junction GaAs thin‐film solar cell exhibits enhanced endurance of ...
