Skyrmions in twisted van der Waals magnets

Skyrmions in twisted van der Waals magnets

Magnetic skyrmions in 2D chiral magnets are in general stabilized by a combination of Dzyaloshinskii-Moriya interaction and external magnetic field. Here, we show that skyrmions can also be stabilized in twisted moir\'e superlattices in the absence of an external magnetic field. Our setup consists of a 2D ferromagnetic layer twisted …
