Abstract
Studies on divalent-metal (M)-atom-doped XNM (X=Si, Ge, and Sn, N=8–12 and 14) clusters, using ab initio pseudopotential plane wave method, show that the well known nine- and ten-atom capped prism units as well as 12- and 14-atom clusters of these elements can transform to magic clusters with higher symmetries and larger highest occupied–lowest unoccupied molecular orbital gaps. Most strikingly doping of X12 with Mn leads to an icosahedral superatom, Mn@X12, X=Ge and Sn with a high magnetic moment of 5 μB, enriching the family of M-doped clusters of semiconductors for possible nanodevice applications.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
