Magnetic Solitons and Thickness‐Dependent Magnetization Reversal in Interconnected Helical Nanowire Arrays (Adv. Phys. Res. 2/2026)

Magnetic Solitons Appear in 3D Interconnected Nanohelices A new study shows how magnetic domain walls and linked vortex-anti-vortex pairs can form in 3D nanowire arrays formed of interconnected helices. In Research Article e00135, Charudatta Phatak and co-workers show how 3D geometric design can control both the solitons that form and the magnetization switching pathway. Demonstration of this highly tunable system shows the potential for using 3D nanomagnets for applications in data storage, unconventional computing, and sensing. The cover image shows an experimental magnetic induction map of a 3D nanowire array obtained through Lorentz transmission electron microscopy.
