Localized Spin Textures Stabilized by Geometry‐Induced Strain in 2D Magnet Fe3GeTe2

open access: yesAdvanced Materials, EarlyView.
Strain engineering in 2D van der Waals ferromagnet Fe₃GeTe₂ is studied using scanning transmission X‐ray microscopy. Spatially varying strain from micropillar arrays induced local 10 K Curie temperature increases, stabilizing magnetic domains including skyrmions and skyrmion bags near pillar corners.

Néel Tensor Torque in Polycrystalline Antiferromagnets

open access: yesAdvanced Materials, EarlyView.
This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a
