tau-phase MnAl (P63/mmc, a=3.887 Å, c=4.277 Å) - metastable RE-free permanent magnet. hP4, 4 atoms/cell. Experimental Tc ~650-700 K, Ms ~350-400 Am2/kg. Fifth structure family in the bias-correction protocol. Closely related to D019 but distinct Wyckoff occupancy.
Row check on tau-MnAl (tau): input CIF is valid, the thermodynamic columns are not. @herme...
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.
