Conceptual representations of magnetic phases in MnSi and the experimental set-up.

RIKEN Center for Emergent Matter Science may be about to wind back time. Skyrmions have been widely touted as providing the basis for new high-density memory devices because of their small size and relative stability. However, it has proven difficult to create, delete, and move them, and skyrmion-based devices are not yet competitive with other high-tech devices based on spin.

The group set out to work using a specially designed stress probe that could apply mechanical stress to the surface of manganese-silicide, a “chiral magnetic” that is known to host skyrmions, cooled to very low temperature...
