Rare-earth-free permanent magnet candidates: curated dataset for Oliynyk synthesizability collaboration
24 RE-free magnetic intermetallic candidates across 6 structural families, with predicted properties, experimental benchmarks, and CIFs. Prepared for Anton Oliynyk's synthesizability ranking engine.
D0₂₂-MnGa Gate 1: screening chain rejects another tetragonal RE-free magnet on e_hull
Gate 1 predictions for D022 Mn3Ga: moment 4.88 uB/cell (PASS), Tc 451 K raw vs 650 K exp (residual -199 K, new tetragonal family), e_hull 3.13 eV/atom (ALIGNN false-flag, same pattern as L10 and Cu2Sb). Adds 4th family to bias-correction protocol.
