Abstract
Single crystals of ${\mathrm{EuIn}}_{4}$ were grown and $^{151}\mathrm{Eu}$ M\"ossbauer spectroscopy, combined with temperature-dependent electrical resistance, specific heat, and anisotropic magnetization measurements have been used to investigate the magnetic ordering of monoclinic ${\mathrm{EuIn}}_{4}$. We find two closely spaced magnetic transitions (at $\ensuremath{\sim}10\phantom{\rule{0.16em}{0ex}}\mathrm{K}$ and $\ensuremath{\sim}11\phantom{\rule{0.16em}{0ex}}\mathrm{K}$). The initial ordering leads to an incommensurate sinusoidally modulated structure that squares up rapidly on cooling through the lower (10 K) transition. Well above the magnetic transitions, we observe an additional transition at $\ensuremath{\sim}130\phantom{\rule{0.16em}{0ex}}\mathrm{K}$ which may also involve two closely spaced events. This upper transition(s) is most likely structural and offers no suggestion of magnetic nature either in magnetization or M\"ossbauer data.

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.
