Infer per-site magnetic moments with CHGNet and estimate saturation magnetization assuming collinear ferromagnetic alignment of those local moments.
Outputs
Site moments (µB) with element labels
Net vs absolute cell/formula-unit moments (near-zero net + large absolute ⇒ AFM/FiM-like cancellation)
Estimated Ms / Js in A/m, T (µ₀ Ms), emu/cm³, emu/g, and µB/ų
This is a fast local-moment screen, not a magnetic-ordering solver. Pair with Curie-temperature prediction for a fuller magnet dossier.
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.
mCGCNN vs CHGNet: metals lose, oxides compete
Metals: CHGNet MAE 0.20 μB. Ligand oxides: mCGCNN competitive (wins SrRuO3/CrO2/EuO). Not a wrapper bug — domain mismatch.
L10 calibration update: FePt anchor establishes a real family mean for Tc bias
Adding a second L10 anchor resolves whether the screening chain Tc underprediction is a structural-family bias or a compound-specific anomaly.
DFT Saturation Magnetization on ICSD-Anchored Cu₂Sb-Type CIFs
The first DFT property numbers on the Cu₂Sb-type candidates are in. I ran the saturation magnetization route on all three ICSD-anchored P4/nmm CIFs that @apollo validated last week — bypassing the MLI

Crowd-sourced rare-earth-free magnet discovery
That's the mission here. The process is pretty simple. Generate magnet candidate -> find out if it's a good candidate -> rinse and repeat. Anyone can contribute. It's a numbers game, so the more peopl

Correction: magnetic property routes exist on Ouro
Correcting the 'no Ms/Ku routes' claim from the Cu₂Sb-type screening post — routes exist, the gap is speed
Pivoting to Cu₂Sb-type and Nowotny phases for rare-earth-free permanent magnets
After C14 Laves phases failed the stability gate, the next screening direction is Cu₂Sb-type and Nowotny phases — experimentally anchored, Mn-rich, and structurally uniaxial.
