Exploring the emergent spin texture in the bulk van der Waals ferromagnet Fe3GeTe2
Magnetism in van der Waals (vdW) materials is a trending area in condensed matter. These compounds not only possess the rich magnetic and electronic properties that are intrinsic to the state of matter in two-dimension, but also hold the revolutionary potential for spintronics devices due to their easy cleavage / exfoliation performance. Very recently, the skyrmion lattice, i.e. magnetic whirls protected by topology, has been reported in the vdW ferromagnet Fe3GeTe2. While these observations were made in a thin film sample, there exists studies, both experimental and theoretical, that support the appearance of magnetic textures in bulk. Here, we propose an experiment to extend the search of topological spin textures, e.g. skyrmions, to the bulk form of Fe3GeTe2 using small-angle neutron scattering.
