Abstract
FeCrAs undergoes a magnetic ordering transition at T N ≃ 125 K. The magnetic structure of FeCrAs, which crystallizes in space group [Formula: see text] and is isostructural to Fe 2 P, was determined by constant wavelength neutron powder diffraction. A single basis function was found to describe the intensity distribution in the magnetic satellite reflections, which are associated with propagation vector k = (1/3, 1/3, 0), representing a K-point zone-boundary ordering. The magnetic intensity could be modelled by moments from Cr only, which lie on the 3g-sites, in pyramidal coordination by As, whereas the moments on Fe, in tetrahedral coordination on the 3f-sites, were found to be so small as to be zero within error. This agrees with previous Mössbauer spectroscopy measurements on this compound. The magnetic structure is characterized by non-collinear antiferromagnetic order of the moments, all of which lie in the hexagonal plane. This does not appear to have been observed in other monopnictides with Fe 2 P structure but is consistent with geometric frustration of antiferromagnetic interactions.

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 it
