Abstract

All-electrical methods for nucleating, detecting, and manipulating spin textures in two-dimensional van der Waals magnets can serve as fundamental building blocks for multi-state spintronic memory, logic, and neuromorphic computing applications. This work demonstrates all-electrical detection of spin textures in Fe₅GeTe₂ using pure spin transport in a lateral graphene spin-valve device at room temperature, where nanoscale constrictions or notches in Fe₅GeTe₂ create spin textures that inject distinct spin polarizations into graphene and produce anomalous multi-level spin-valve switching and Hanle spin precession signals.
