The realization of chiral spin textures,
comprising myriad distinct,
nanoscale arrangements of spins with topological properties, has established
pathways for engineering robust, energy-efficient, and scalable elements
for non-volatile nanoelectronics. Particularly, current-induced manipulation
of spin textures in nanowire racetracks and tunnel junction based
devices are actively investigated for applications in memory, logic,
and unconventional computing. In this Article, we paint a background
on the progress of spin textures, as well as the relevant state-of-the-art
techniques used for their development. In particular, we clarify the
competing energy landscape of chiral spin texturesskyrmions
and chiral domain walls, to tune their size, density, and zero-field
stability. Next, we discuss the spin texture phenomenology and their
response to extrinsic factors arising from geometric constraints,
interwire interactions, and thermal-electrical effects. Finally, we
reveal promising chiral spintronic memory and neuromorphic devices
and discuss emerging material and device engineering opportunities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
