Story summary

Researchers demonstrated that in-plane magnetic fields can switch skyrmion chirality and improve lattice order in chromium tribromide (CrBr3).
This control enables organization of skyrmion arrays without high currents, advancing magnetic logic and memory chip prospects.
Weak magnetic fields lower energy barriers, enabling spontaneous chirality flips and removal of defects.
As chirality switches, skyrmion bubbles transition from disordered to a hexatic phase, with potential benefits for magnetic memory and neuromorphic computing.
