Abstract

fetched live from OpenAlex

D3OFe3(SO4)2(OD)6 is a model example of an S = 5/2 Kagome anti-ferromagnet that exhibits unconventional two-dimensional spin-glass properties. We report quasi-elastic neutron-scattering data on D3OFe3(SO4)2(OD)6 derived from three-directional neutron spin-polarization analysis in combination with time-of-flight analysis (Δ E [Formula: see text] 1 meV). At 1.5 K, within the time window of the experiment, only 45% of the total elastic magnetic moment is frozen — a broad magnetic response in Q is still observed at temperatures in excess of ten times the spin-glass freezing temperature. The dc-magnetization measurements on H3OFe3–xAlx(SO4)2(OD)6 show that dilution of the magnetic lattice with Al3+ disrupts the spin-glass state. Mössbauer measurements indicate that the Al replaces the Fe ions on the magnetic sites of the Kagome lattice, giving rise to two distinct iron sites with equal occupation levels but different hyperfine fields. PACS Nos.: 75.10N, 75.30C, 75.30H, 75.50L

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.
