Description
Meng Wang and co-authors produce a zero-field anomalous Hall effect in a doped antiferromagnetic metal by rebuilding its magnetic order, in a study from 2023. The Hall effect in such magnets promises rich physics and devices, but a leading candidate material, ruthenium oxide, forbids the effect at zero field. Its internal arrows, the Néel vector, point along a direction protected by symmetry.
Adding chromium in place of some ruthenium turned the vector to a new direction while keeping the antiparallel order intact. Transport tests, magnet measures, and theory matched on the change. The resulting Hall signal had no net magnetization behind it and rotated as the theory predicted. The authors present doping as a practical lever on this effect.
