Structure and Physical Properties of Ternary Antimonide YbCrSb<sub>3</sub>
Bibliographic record
Abstract
The ternary rare-earth antimonide YbCrSb 3 was prepared by arc-melting of the elements. Its structure was determined by single-crystal X-ray diffraction (Pearson symbol oP 20, orthorhombic, space group Pbcm, Z = 4, a = 12.981(3) Å, b = 6.140(1) Å, c = 5.993(1) Å). YbCrSb 3 is isostructural to LaCrSb 3 and CeCrSb 3, and extends the RE CrSb 3 series (previously known for RE = La, Ce, Pr, Nd, Sm, Gd, Tb, Dy) to the latest rare-earth member yet and to one that is essentially divalent instead of trivalent. Electrical resistivity measurements on single crystals and magnetic susceptibility measurements on powders revealed a magnetic ordering transition at T C = ∼280 K, the highest observed so far in the RE CrSb 3 series. The isothermal magnetization at 100 K indicated an approach to saturation, but with low values (0.08 μ B /mol at 9 T). These results suggest a ferromagnetic or canted antiferromagnetic structure.

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.
