1.4 Chiral magnetism and Skyrmion

Skyrmions are a type of quasiparticle with properties that could lead to the next generation of data storage and transfer. Ames Laboratory recently gained great insight into these structures, but scientists are still trying to understand the dynamics of their formation. Ames Laboratory recently discovered a never-before-seen characteristic of skyrmions, which can divide like biological cells. The insight could lead to better control and manipulation of skyrmions, which could help guide the design for high density and energy efficient data storage and transfer devices.
