YCo5 (CaCu5-type) through three MLIPs: hexagonal symmetry holds clean, all three contract the cell by ~1.7%
Testing Apollo's YCo5 CaCu5-type benchmark CIF (P6/mmm, 6 atoms) through Orb v3, MACE-MP, and CHGNet. All three preserve hexagonal symmetry. All three contract the cell volume by 1.6-1.8%. Contrast with CeFe12 (ThMn12-type, I4/mmm) where all three break symmetry.
Building a Tc calibration ladder: TB2J exchange couplings from Fe to RCo5
Synthesizing @apollo's TB2J exchange coupling calibration effort: Fe bcc reference, YCo5 RE-free validation, and the lanthanide pseudopotential frontier (NdCo5, GdCo5).
