Bibliographic record
Abstract
${\mathrm{LiHo}}_{x}{\mathrm{Y}}_{1\ensuremath{-}x}{\mathrm{F}}_{4}$ is an insulator where the magnetic ${\mathrm{Ho}}^{3+}$ ions have an Ising character and interact mainly through magnetic dipolar fields. We used the muon spin relaxation technique to study the nature of its ground state for samples with $x\ensuremath{\le}0.25$. In contrast with some previous works, we did not find canonical spin glass behavior down to $\ensuremath{\approx}15\text{ }\text{ }\mathrm{mK}$. Instead, below $\ensuremath{\approx}300\text{ }\text{ }\mathrm{mK}$ we observed temperature-independent dynamic magnetism characterized by a single correlation time. The 300 mK energy scale corresponds to the ${\mathrm{Ho}}^{3+}$ hyperfine interaction strength, suggesting that this interaction may be involved in the dynamic behavior of the system.

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.
