To develop and evaluate a simplified approach for writing and deleting magnetic skyrmions using electrical pulses in a two-terminal nanowire device.
Fabricated two-terminal nanowire devices operated with conventional electrical current pulses.
Applied X-ray microscopy to capture direct, real-space imaging of skyrmion creation and annihilation.
Conducted micromagnetic simulations to identify the physical mechanisms driving skyrmion manipulation.
Demonstrated reliable skyrmion writing driven by pulse-induced Joule heating.
Achieved selective skyrmion deletion mediated by current-induced Oersted magnetic fields, confirming spatial and temporal control.
