Terrace-Edge-Induced Domain Nucleation In their Research Article (10.1002/adfm.202516597), Hee-Sung Han and co-workers show that terrace edges in 2D magnetic van der Waals heterostructures initiate the nucleation of magnetic domains. Magnetic transmission X-ray microscopy combined with micromagnetic simulations uncovers how terrace geometry modulates the local magnetic energy landscape, enabling controlled domain formation at room temperature.
Lee et al. (Sun,) studied this question.
