Abstract :
This article presents an approach to control domain wall dynamics in ferromagnetic nanorings via local variations of spatially varying domain wall energy. Time-resolved scanning transmission X-ray microscopy is used to investigate the domain wall dynamics and micromagnetic simulation is performed to verify the experimental results.
