Bibliographic record
Abstract
Magnetic and transport properties have been measured for the series of ternary rare-earth germanium antimonides RE 6 Ge 5 - x Sb 11+ x ( RE = La−Nd, Sm, Gd−Dy). All are metallic, with the members containing RE other than La displaying kinks in their resistivity vs temperature curves; the Tb and Dy members exhibit Kondo-like behavior with resistivity minima occurring at 10 and 150 K, respectively. For the compounds with RE = Ce, Pr, Nd, Sm, Gd, Tb, the magnetic susceptibility and electrical resistivity measurements reveal long-range antiferromagnetic ordering with T N ≤ 22 K. At 2 K, the Ce, Pr, and Nd members undergo metamagnetic transitions at critical fields between 1.0 and 4.0 T, while the Gd member displays spin-flop behavior with H SF = 1.85 T and H C = 5.75 T. The single-crystal magnetoresistance of the Gd member below T N shows an orientationally dependent steplike behavior of resistivity as a function of field with changes in resistivity coinciding with the same critical fields observed in the magnetization measurements.

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; both teacher heads agree on what is shown here.
