Phys.org has reported:

Magnetic skyrmions are swirling magnetization patterns that form in certain materials and can be moved using relatively little energy. Optical skyrmions can control their motion, according to the source headline.

Magnetic skyrmions behave in many ways like particles, with stable internal structures and distinct boundaries. Their small size and low energy needs make them promising information carriers for emerging technologies, including low-power memories and logic circuits.

Researchers have pursued practical methods to control the skyrmions’ movement with high precision.
