<i>μ</i><sup>+</sup>SR study on triangular antiferromagnet LiCrO<sub>2</sub>
Bibliographic record
Abstract
In order to elucidate the magnetic nature of the lithium chromium dioxide LiCrO2, in which the Cr3+ ions form a two-dimensional triangular lattice in the CrO2 plane, we have performed a positive muon-spin rotation and relaxation (μ+SR) experiment using a powder sample at the temperatures below 155 K. Weak-transverse-field measurements indicated the existence of a bulk antiferromagnetic (AF) transition at TN=61.2 K. The ZF-μ+SR measurements indicated that LiCrO2 is a pure paramagnet for T ≥ 62.5 K, since its internal magnetic field (Hint) can be explained by solely nuclear magnetic moments. This means that, contrary to previous suggestions by susceptibility and heat capacity measurements, no short-range order exists for T ≥ 62.5 K. However, ZF-μ+SR detected the change in Hint from a low-T static state to a high-T dynamic state at 115 K, most likely connected to a change in the position/motion of the Li ions.

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; a candidate call from one teacher head, not a consensus.
