What to know about Real-time measurements reveal antiferromagnetic skyrmions move in line with an applied current

Researchers at Johannes Gutenberg University Mainz have used time-resolved X-ray microscopy to demonstrate that antiferromagnetic skyrmions move in straight trajectories aligned with electric currents. This finding confirms theoretical predictions that these systems lack the skyrmion Hall effect, potentially enabling more reliable spintronic devices.
