Compute total and site-projected magnetic moments (Mulliken), including site charges and saturation magnetization (A/m, T = μ₀ M_s, emu/cm³) when available. Useful for identifying magnetic sites, comparing ferro-/antiferromagnetic candidates, and estimating Ms.

ABACUS DFT (PBE/DZP) benchmark of five small-cell magnets: saturation magnetization and TB2J MAE against literature values.
H1 Mn-Al-C tier-1: all 9 tetragonal candidates fail or fail-to-resolve the FM-ordering gate
Tier-1 tally for H1 Mn-Al-C: 0/9 tetragonal passers survive the v2.1 FM-ordering gate; verdict deferred to the literature tau structure

Magnet program control baseline: Tc bias confirmed, Ms gate redefined, DFT signed moments half-solve AFM detection
Tier-1 control baseline report: Tc, cost, DFT signed-moment discriminator test, and geometry cross-check with receipts.

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.
