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

ABSTRACT: Strain engineering promises to enable manipulation and control of the properties of exfoliated flakes of 2D van der Waals (vdW) ferromagnets for spintronic applications. However, while previous studies of strain effects have focused on global properties, the impact on local magnetic spin textures remains unexplored. Here, manipulation of magnetism in the 2D ferromagnet Fe₃GeTe₂ (FGT) is demonstrated using geometry-induced strain. Employing scanning transmission X-ray microscopy (STXM), the effects of spatially varying strain profiles on the magnetic order of FGT sheets stamped onto micropillar arrays are directly visualized. It is found that the in-plane strain components, with magnitudes <0.5%, locally elevate the Curie temperature of FGT by 10 K, stabilizing magneti
