Abstract

Skyrmions are particle-like magnetic structures which could form an important component of future spintronic devices but greater control over their physical characteristics must first be achieved. Here, using micromagnetic simulations, the authors report pixelated skyrmions showing how to engineer their position, size, and shape using a current pulse.
