摘要
Magnetic skyrmions are topological spin configurations that hold potential as 'bits' in ultra-dense memory and information processing. In this work, we study the destructive effect of magnetic defects on the stability of skyrmions using micromagnetic simulations, and suggest two methods to manipulate this effect. Based on this, we design a voltage-controlled skyrmion deletion device, and further propose a data modification scheme for the skyrmion-based racetrack memory. These results provide an important orientation for skyrmion applications in storage and computation fields.
