Version of
RE-free permanent magnet candidates
Single working shortlist of 250 RE-free permanent-magnet candidates ranked deterministically for laboratory triage. Requires a CIF and calculated saturation magnetization; MAE, Curie temperature, and hull distance are retained when available and missing evidence is explicitly penalized via `evidence_coverage`. Score weights: magnetic 0.40, synthesizability 0.30, supply concentration (HHI) 0.15, toxicity 0.15. CIF and source-dataset references are native links. Generated by rank-re-free-magnets v5; config fingerprint 319914cfce92.
