This research investigates domain wall movement in cylindrical nanowires under current pulses, implying thermal effects are crucial for spintronic device design.
Key Points
The aim is to understand how domain walls behave in cylindrical nanowires when subjected to current pulses.
Used X-ray Magnetic Circular Dichroism and Photoemission Electron Microscopy to study dynamics.
Applied nanosecond current pulses to cylindrical magnetic nanowires.
Analyzed domain wall motion and rebound behavior based on current density variations.
Small current densities effectively move and saturate the domain walls.
At higher current densities, domain walls rebound instead of being expelled.
Rebound distance of domain walls increases with longer pulse durations.
