Fig. 4

a Sample for Lorentz transmission electron microscopy measurements consisting of 2L WTe2 and 30L Fe3GeTe2. Scale bar: 10 μm. b Typical labyrinth domain in 30L Fe3GeTe2 thin flakes. Scale bar: 2 μm. c From the aligned and stripe-like domain structures of the WTe2/Fe3GeTe2, a Dzyaloshinskii–Moriya interaction energy is estimated to be  ~1.0 mJ m−2. Scale bar: 2 μm.
