Abstract
The ternary ${\mathrm{Gd}}_{5}{\mathrm{Si}}_{x}{\mathrm{Sn}}_{4\ensuremath{-}x}$ alloy system has been shown to exist for all x. Structural and magnetic phase diagrams have been derived. Si-rich and Sn-rich alloys are orthorhombic and order ferromagnetically, with ${T}_{c}$ increasing with Si content. Intermediate compositions are monoclinic, and exhibit a disordered noncollinear magnetic order. In the ordered state, ${}^{119}\mathrm{Sn}$ M\"ossbauer spectroscopy shows transferred hyperfine fields approaching 37 T at Sn sites in the orthorhombic form, and severely broadened spectra with much smaller fields in the monoclinic form. For $x<~0.4,$ there is, on heating, a first-order magnetic and structural transition from a ferromagnetic to a nonmagnetic state that may be associated with a giant magnetocaloric effect.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
