Neutron scattering study of the layered Ising magnet CsDy(MoO4)2
Bibliographic record
Abstract
The quasi-two-dimensional antiferromagnet CsDy(MoO4)2 is studied by neutron diffraction and quasielastic neutron scattering. The crystal structure of two low-temperature phases (below 120 K and below 40 K) is determined. An approximate structure of the magnetically ordered phase (TN=1.36 K) is proposed. In the ordered state the order-parameter critical exponent β=0.17(0.01), the in-plane correlation length exponent ν=0.94(0.07), and the staggered susceptibility critical index γ=1.01(0.04) were determined. Comparing these results to the exact solution for a 2D Ising magnet, we conclude that, although 2D behavior is apparent in CsDy(MoO4)2, there are deviations from the simple 2D Ising model.

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.
