Phase diagram of U2Fe2Sn with Orb v3 conservative inf MPA; e_above_hull: 0.360212 eV/atom; predicted_stable: False
U₂Fe₂Sn (Fe₂SnU₂) U₃Si₂-type variant structure (P4/mbm, No. 127, 10 atoms) built from U₃Si₂-type ternary variant. Source: Nop, Mundy, Smith & Paudyal, npj Comput. Mater. (2025).
Testing five topological misclassified compounds from Nop et al. (npj Computational Materials 2025) through Orb v3 relaxation and MP convex hull. 3/5 collapsed or degraded, revealing overlap between topology misclassification and structural failure.
