Analog to the <sup>4</sup>He melting curve in a model geometrically frustrated magnet
Bibliographic record
Abstract
Gadolinium gallium garnet, Gd 3 Ga 5 O 12 (GGG) has an extraordinary low-temperature phase diagram. Although the CurieWeiss temperature of GGG is ~2 K, GGG shows no long-range order down to T ~ 0.4 K. At low temperatures GGG has a spin-glass phase at low fields ([Formula: see text] 0.08 T), a field-induced long-range-ordered anti-ferromagnetic (AFM) phase at fields of between 0.7 and 1.3 T, and, at intermediate fields, an apparent spin-liquid (SL) phase without long-range order. We have performed specific heat, magnetocaloric, and static magnetization measurements near the SL/AFM phase boundary. Our results show that the lower field boundary of the AFM phase has a distinct minimum at T ~ 0.2 K, in analogy to the minimum in the melting curve of 4 He. PACS Nos.: 75.30Kz, 75.50Ee

How this classification was reachedexpand
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.
