Abstract

fetched live from OpenAlex

We have determined the magnetic structures of the Er and Fe sublattices in ErFe6Sn6 by high-resolution neutron powder diffraction and Mössbauer spectroscopy on the 166Er, 57Fe and 119Sn 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 CP m'c'm' and a propagation vector [010]. The Fe magnetic moment at 1.5 K is 2.4 ± 0.6 μB. 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 Er3+ magnetic moment (determined by a combination of neutron diffraction and magnetization measurements) are 5.9 ±0.1 and 4.9 ±1.5 μB, respectively, yielding a net Er moment of 7.7 ± 1.5 μB. The Er3+ magnetic moment derived from 166Er Mössbauer spectroscopy is 8.5(1) μB.

Full frame distilled prediction

Teacher imitation

Not 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.
