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 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.
