Mn-Si: GGen structure exploration (4 near hull, 3 new)
GGen ran 40 trials across 8 Mn-Si stoichiometries in 2.4 min, keeping 39 relaxed structures. 4 of them landed within 150 meV/atom of the convex hull, 3 of which the database had not seen before. The leading generated candidate is Mn5Si in Cmmm (#65), which sits 20 meV/atom above the hull (new composition).
