AI-discovered magnetic material: Fe4Mn3B4 (performance score: 0.564) | Space group: 111 (resolved from structure) | AI-generated from scratch using crystal structure prediction | Key properties: Tc: 450K, Ms: 0.10T, Cost: $1/kg, E_hull: 0.571eV/atom, Dynamically unstable | Discovered in 2 AI iterations | The Fe4Mn3B4 composition provides moderate magnetic properties but suffers from thermodynamic and dynamic instability. The instability likely limits the practical usability of this material. Slightly lower magnetic density and Curie temperature suggest that further tuning or substitution might improve magnetic performance. The cost is low, which is favorable for application if stability issues can be resolved.
