Magnetic ordering in ErFe<sub>6</sub>Sn<sub>6</sub>
Bibliographic record
Abstract
We have determined the magnetic structures of the Er and Fe sublattices in ErFe 6 Sn 6 by high-resolution neutron powder diffraction and Mössbauer spectroscopy on the 166 Er, 57 Fe and 119 Sn isotopes. The crystal space group is orthorhombic Cmcm . The Fe sublattice is antiferromagnetic with a Néel temperature of 560(5) K and it orders along the [100] direction with a magnetic space group C P m ' c ' m ' and a propagation vector [010]. The Fe magnetic moment at 1.5 K is 2.4 ± 0.6 μ B . The Er sublattice orders independently of the Fe sublattice at 4.8 ±0.4 K and comprises a ferromagnetic mode along [100] and an antiferromagnetic mode along [010], with a propagation vector [01/20] i.e. cell-doubling along [010]. The magnetic space group of the Er sublattice within the magnetic unit cell is Pbc ' m ' , a subgroup of Cmcm . At 1.5 K the ferromagnetic and antiferromagnetic components of the Er 3+ magnetic moment (determined by a combination of neutron diffraction and magnetization measurements) are 5.9 ±0.1 and 4.9 ±1.5 μ B , respectively, yielding a net Er moment of 7.7 ± 1.5 μ B . The Er 3+ magnetic moment derived from 166 Er Mössbauer spectroscopy is 8.5(1) μ B .

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.
