The promise of high-density and low-energy-consumption devices motivates thesearch for layered structures that stabilize chiral spin textures such astopologically protected skyrmions. At the same time, layered structures providea new platform for the discovery of new physics and effects. Recentlydiscovered long-range intrinsic magnetic orders in the two-dimensional van derWaals materials offer new opportunities. Here we demonstrate theDzyaloshinskii-Moriya interaction and N\'eel-type skyrmions are induced at theWTe2/Fe3GeTe2 interface. Fe3GeTe2 is a ferromagnetic material with strongperpendicular magnetic anisotropy. We demonstrate that the strong spin orbitinteraction in 1T'-WTe2 does induce a large interfacial Dzyaloshinskii-Moriyainteraction at the interface with Fe3GeTe2 due to the inversion symmetrybreaking to stabilize skyrmions. Transport measurements show the topologicalHall effect in this heterostructure for temperatures below 100 K. Furthermore,Lorentz transmission electron microscopy is used to directly image N\'eel-typeskyrmions along with aligned and stripe-like domain structure. This interfacialcoupling induced Dzyaloshinskii-Moriya interaction is estimated to have a largeenergy of 1.0 mJ/m^2, which can stabilize the N\'eel-type skyrmions in thisheterostructure. This work paves a path towards the skyrmionic devices based onvan der Waals heterostructures.
