Abstract
Wide band gap semiconductors doped by transition metals are attracting much attention in part because ofpossible ‘spintronics’ applications. Using pseudo-potential plane-wave calculations and density functional theory(DFT), we studied effects of doping Mn of various concentrations on the cubic silicon carbide structure (?-SiC).Band structures and density of states (DOSs) were calculated for ?-SiC and Si1-xMnxC (with x= 0.0313, 0.0625,and 0.25). Analyses of the DOSs revealed that the diluted ferromagnetic semiconductor Si1-xMnxC, i.e. SiC withMn substituted for Si, should be a half-metal. Our results show spin polarization at Fermi energy (Ef), and astable ferromagnetic state for x= 0.0625.

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
