“…The ability to host such domains in these materials opens new opportunities to control their behavior through interfacial interactions such as strain 10 or spin orbit coupling. 11 The skyrmions in these materials are typically formed when field-cooling the sample through the Curie temperature, and exist in large groups that can be ordered or disordered. The collective behavior of skyrmions is only recently being investigated such as formation of hexatic phases during phase transformation.…”

Van der Waals ferromagnets are an intersting class of materials for exploring fundamental physics of magnetic order in the 2D limit as well as for technological applicaitons due to possibility of creating novel heterostructures. These materials have shown to host magnetic skyrmion lattices with their organization controlled by the magnetic properties such as anisotropy, exchange, and Dzyaloshinkii-Moriya interaction. For technological applications, it is also necessary to understand to the behavior of skyrmions in response to electric currents. In this work, we show the effect of electric current pulses on the magnetic skyrmions formed in Fe 3 GeTe 2 which has a Curie temperature of 220 K. We demonstrate via real-space in situ imaging using Lorentz transmission electron microscopy (LTEM) the effect of temperture and pulse width.
