Description
Minhyuk Choi and nine colleagues report a giant Hall effect in a magnet built on a kagome lattice, a grid of corner sharing triangles. In such materials, electrons veer sideways in ways tied to the bend of their quantum paths. The compound studied, YMn6Sn6, orders its magnetism against itself. Strong magnetic fields tilt those spins, and the tilt reshapes key electron bands near the Fermi level.
That reshaping sent the sideways conductivity to a level among the highest yet seen in magnets, far past what static theory predicts. Part of the surge came from electrons being scattered unevenly in this very clean crystal. Choi and the team say field tuned spin tilt offers a knob for dialing topological responses in future spin devices.
