Small Pt Hall sensors on Cr2O3 crystals detect single-domain Néel vector reorientation at the spin-flop transition, and magnetoelectric cooling deterministically sets the Néel vector direction.
The overall temperature dependence exhibits a broad maximum around 100 K

Electrical Detection of Single-Domain N\'eel Vector Reorientation across the Spin-Flop Transition in Cr2O3 Crystals
Small Pt Hall sensors on Cr2O3 crystals detect single-domain Néel vector reorientation at the spin-flop transition, and magnetoelectric cooling deterministically sets the Néel vector direction.
