Skyrmion dynamics in moiré magnets

We consider a twisted magnetic bilayer subject to the perpendicular electric field. The interplay of induced Dzyaloshinskii-Moriya interaction and spatially varying moir\'e exchange potential results in complex noncollinear magnetic phases in these structures. We numerically demonstrate the coexistence of intralayer skyrmions and bound interlayer skyrmion pairs and show that they are characterized by distinct dynamics under the action of external in-plane electric field. Specifically, we demonstrate the railing behavior of skyrmions along the domain walls which could find applications in spintronic devices based on van der Waals magnets.
