Current-induced domain wall motion in the van der Waals ferromagnet Fe3GeTe2

Magnetism in two-dimensional (2D) materials has attracted much attention, especially the recently observed stabilization of magnetic chiral nanostructures (Adv. Mat. 34.11 (2022): 2108637) in the high Curie temperature ferromagnet Fe₃GeTe₂. These magnetic nanostructures are promising as potential memory bits for next-generation spintronic devices, such as racetrack memory. Here, the current-induced magnetic domain wall in exfoliated few-layer thick Fe₃GeTe₂ flakes is investigated using variable temperature Kerr microscopy. Triggered by nanosecond current pulses, spin-transfer- and spin-orbit- torques are found to induce reliable and efficient domain wall motion. Going beyond conventional ferromagnetic metals, the clear observation of current induced domain wall motion demonstrates the potential of 2D magnetic materials for spintronics applications.
