Laser-induced topological spin switching in a 2D van der Waals magnet

Abstract

Van der Waals magnetic materials, which maintain their magnetic ordering down to a monolayer have been found to host a variety of spin textures, including topological spin textures such as skyrmions. Here, Khela et al. demonstrate laser induced topological switching, between skyrmions, anti-skyrmions and stripe domains in CrGeTe3.
