Topological Spin‐Texture Transitions in van der Waals Magnets Revealed by X‐Ray Fourier Transform Holography

Advanced Materials, EarlyView.
Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Spectrally Programmable Spin‐Polarized Photocurrents in WSe2–NiPS3 Magnetic van der Waals Heterostructures

Advanced Materials, EarlyView.
Heterostructure photodiode devices of p‐type WSe2 with n‐type NiPS3 constructs spectrally protected spin‐polarized photocurrents. The energy of the excitation photon serves as an independent control parameter for spin‐selective photocurrent generation. ABSTRACT Efficient generation and control of spin‐polarized currents in semiconductors remain central

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...
