Magnetization and<sup>61</sup>Ni Mössbauer effect study of the ternary arsenide CrNiAs
Bibliographic record
Abstract
The results of x-ray diffraction, dc magnetization, and 61 Ni Mössbauer spectroscopy studies of the ternary arsenide CrNiAs are reported. This compound crystallizes in the orthorhombic Fe 2 P-type structure (space group ) with the lattice parameters a = 6.1128(2) Å and c = 3.6585(1) Å. CrNiAs is a mean-field ferromagnet with Curie temperature T C = 171.9(1) K and the critical exponents β = 0.514(18), γ = 1.010(16), and δ = 2.922(10). The temperature dependence of the magnetic susceptibility above T C follows the modified Curie–Weiss law with a paramagnetic Curie temperature of 176.0(3) K and effective magnetic moment per transition metal atom of 2.42(1) μ B . The magnetic moment per formula unit at 4.2 K is found to be 1.114(33) μ B . The hyperfine magnetic field at 61 Ni nuclei at 4.2 K of 41.5(1.0) kOe implies that the Ni atoms carry a magnetic moment of 0.15(3) μ B , and that the moment carried by the Cr atoms is 0.95(6) μ B . The Debye temperature of CrNiAs is 221(1) K.

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.
