Magnetic and Transport Properties of Ferromagnet NdCrSb<sub>3</sub>
Bibliographic record
Abstract
NdCrSb 3, a compound containing alternating layers of Nd and Cr atoms in its structure, undergoes two ferromagnetic ordering transitions. At 107.8 K, ferromagnetic ordering of the Cr moments occurs; at 12.7 K, ferromagnetic ordering of the Nd and Cr moments occurs. Neutron diffraction studies place the magnetization axis for the ordered Cr moments along [010], and for the coupled Nd and Cr moments along [100]. These transitions are also observed in the temperature dependence of the dc magnetization, and as maxima in the χ‘ ac and χ‘ ‘ ac magnetic susceptibilities. Hysteresis loops at 2 and 40 K revealed saturation magnetization values of 3.70 and 2.37 μ B /f.u. and coercive fields of 2100 and 400 Oe, respectively. The saturation magnetization of 3.7 μ B at 2 K is the same as that determined from neutron diffraction studies. Both ferromagnetic ordering transitions are manifested as kinks in the temperature dependence of the electrical resistivity. Field-dependent resistivity measurements made between 2 and 130 K indicate negative magnetoresistance behavior with values up to −13%.

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.
