Orb-relaxed Fe84 Si12 B40 boride candidate. CIF SHA256 0c038b115f2a049351ed3a9ad88923d0f9d81d8f67d0bfcedd65030c7d5b7ccf. Unconstrained variable-cell ML relaxation; no DFT. Ouro same-formula novelty, hull stability and magnetic performance remain under review; cross-composition framework novelty is separate. Derived from published source: . Known scaffold reference ; authored-parent input SHA256 . Terms: See CIF attribution. Published parent framework; the authored mutation is not an experimentally established material.
