Abstract

fetched live from OpenAlex

The magnetic structures of the CeScSi-type GdMgSn and GdMgPb compounds have been studied by both neutron powder diffraction and M\"ossbauer spectroscopy (${}^{119}Sn$ and ${}^{155}Gd$). The neutron diffraction results show that the two compounds adopt incommensurate antiferromagnetic structures at 5.4 K with propagation vectors $\stackrel{P\vec}{k}=[0.910,0.077,0]$ for GdMgSn and $\stackrel{P\vec}{k}=[0.892,0,0]$ for GdMgPb. The magnetic moments lie in the basal plane, which is confirmed by both ${}^{119}Sn$ and ${}^{155}Gd$ M\"ossbauer spectroscopy. M\"ossbauer spectroscopy refinements and simulations reveal that the magnetic structure of GdMgSn is cycloidal at low temperature and undergoes a transition to a modulated magnetic structure above $T\ensuremath{\sim}40$ K. A similar magnetic transition is inferred for GdMgPb. The magnetic structures of GdMgSn and GdMgPb are compared with those of other CeScSi-type compounds.

Not 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.
