Abstract
${}^{57}\mathrm{Fe}$ and ${}^{119}\mathrm{Sn}$ M\"ossbauer spectroscopy has been used to study local spin correlations in site-frustrated $a\ensuremath{-}({\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Mn}}_{x}{)}_{78}{\mathrm{Sn}}_{2}{\mathrm{Si}}_{6}{\mathrm{B}}_{14}$ alloys. Comparison of total magnetization, hyperfine fields at the magnetic Fe, and nonmagnetic Sn sites shows that the Mn moments order antiparallel to the majority Fe moments and that the order established at the transverse spin freezing transition, ${T}_{\mathrm{xy}},$ exhibits strong antiferromagnetic correlations in the plane perpendicular to the ferromagnetic axis. This result stands in strong contrast with the bond-frustrated case of $a\ensuremath{-}{\mathrm{Fe}}_{100\ensuremath{-}x}{\mathrm{Zr}}_{x},$ but is fully consistent with recent numerical simulations of short-ranged models. The clear difference between site- and bond-frustrated systems below ${T}_{\mathrm{xy}}$ demonstrates the importance of short-range interactions in real spin-glass systems.

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.
