Abstract

fetched live from OpenAlex

Magnetic correlations near the magnetostructural phase transition in the bilayer iron-pnictide parent compound, ${\text{BaFe}}_{2}{\text{As}}_{2}$, are measured. In close proximity to the antiferromagnetic phase transition in ${\text{BaFe}}_{2}{\text{As}}_{2}$, a crossover to three-dimensional critical behavior is anticipated and has been preliminarily observed. Here we report complementary measurements of two-dimensional magnetic fluctuations over a broad temperature range about ${T}_{N}$. The potential role of two-dimensional critical fluctuations in the magnetic phase behavior of ${\text{BaFe}}_{2}{\text{As}}_{2}$ and their evolution near the anticipated crossover to three-dimensional critical behavior and long-range order are discussed.

Full frame distilled prediction

Teacher imitation

Not 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.
