Magnetic skyrmions (MSks) are swirling patterns of magnetization that form inside certain magnetic materials. They can behave like actual particles in many ways, exhibiting a stable internal structure and distinct boundaries. Because they are extremely small and can be pushed around with relatively little energy, MSks are regarded as promising information carriers in emerging technologies, including low-power memories and logic circuits.
However, a major goal in the field has been to find practical ways to control their motion with high precision.
