Orb-relaxed Fe26 Si4 B12 boride candidate. CIF SHA256 455ab92fc1c0d9efe36e9c4d01205d0c31c82cec3862d75fb371f4799f667e65. 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.
