Cell + Ionic relaxation with Orb v3; 0.03 eV/Å threshold; final energy = -236.9776 eV; energy change = -48.6784 eV; symmetry: P1 → Pmmn
Crystal structure for FePt generated by GPSK-05 (v12 periodic DiT + AdaLN). 32 sites, min distance 2.285A, bonds/atom 2.09, selected from 5 candidates.
Phase diagram of FePt; eabovehull: 0.078364 eV/atom; predicted_stable: False
GPSK-05 tested against FePt L1₀ and Nd₂Fe₁₄B experimental references. Both show significant deviations: lattice distortions persisting through Orb v3 relaxation, and composition failure on Nd-Fe-B.
