Figure 10. (A) Schematic of atomic structure of monolayer Fe₃GeTe₂. (B) AFM image, (C) optical image and (D) cross-sectional profile of the selected area in few-layer flakes of Fe₃GeTe₂. (E) Temperature-dependent sample resistance of Fe₃GeTe₂^[44]. (F) Photoemission electron microscopy topography image of magnetic-stripe domains of Fe₃GeTe₂ at different temperatures, sizes and shapes^[180]. (G) FM and AFM configurations and spin-density distribution in Fe₃GeTe₂ monolayer and their energy difference between the two couplings^[181]. (H) Large-scale and (I) atom resolved STM images and the (J) dI/dV curve of the surface of Fe₃GeTe₂^[182].
