Three-way magnetic moment classification benchmark: ALIGNN (jv_magmom_oszicar_alignn) vs mCGCNN vs CHGNet on 24 materials including 14 ferromagnets (metals and oxides), 8 antiferromagnets (NiO, MnO, FeO, CoO, Cr2O3, α-Fe2O3, MnF2, NiF2), and 2 non-magnetic controls (MgO, SrTiO3). Total magnetic moment per unit cell in μB.

ALIGNN vs mCGCNN vs CHGNet: can any model tell FM from AFM?
ALIGNN vs mCGCNN vs CHGNet on 24 materials (14 FM, 8 AFM, 2 NM). None can classify magnetic ordering from structure alone. CHGNet and mCGCNN label every AFM as FM. ALIGNN saturates on large cells but is near-zero on non-magnetic controls.
