Abstract
The correlation between magnetic and structural transitions in ${\mathrm{Gd}}_{5}{\mathrm{Si}}_{x}{\mathrm{Ge}}_{4\ensuremath{-}x}$ hampers the studies of valence electron concentration (VEC) effects on magnetism. Such studies require decoupling of the VEC-driven changes in the magnetic behavior and crystal structure. The designed compounds, ${\mathrm{Gd}}_{5}{\mathrm{GaSb}}_{3}$ and ${\mathrm{Gd}}_{5}{\mathrm{GaBi}}_{3}$, adopt the same ${\mathrm{Sm}}_{5}{\mathrm{Ge}}_{4}$-type structure as ${\mathrm{Gd}}_{5}{\mathrm{Ge}}_{4}$ while the VEC increases from $31\text{ }\text{ }{e}^{\ensuremath{-}}/\mathrm{formula}$ in ${\mathrm{Gd}}_{5}{\mathrm{Ge}}_{4}$ to $33\text{ }\text{ }{e}^{\ensuremath{-}}/\mathrm{formula}$ in ${\mathrm{Gd}}_{5}{\mathrm{GaPn}}_{3}$ (Pn: pnictide atoms). As a result, the antiferromagnetic ground state in ${\mathrm{Gd}}_{5}{\mathrm{Ge}}_{4}$ is tuned into the ferromagnetic one in ${\mathrm{Gd}}_{5}{\mathrm{GaPn}}_{3}$. First-principles calculations reveal that the nature of interslab magnetic interactions is changed by introducing extra $p$ electrons into the conduction band, forming a ferromagnetic bridge between the adjacent $_{\ensuremath{\propto}}^{2}[{\mathrm{Gd}}_{5}{T}_{4}]$ slabs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
