Abstract

fetched live from OpenAlex

Neutron scattering measurements on the spin-ice candidate material ${\mathrm{H}\mathrm{o}}_{2}{\mathrm{R}\mathrm{u}}_{2}{\mathrm{O}}_{7}$ have revealed two magnetic transitions at $T\ensuremath{\sim}95$ and $\ensuremath{\sim}1.4\text{ }\mathrm{K}$ to long-range ordered states involving the Ru and Ho sublattices, respectively. Between these transitions, the ${\mathrm{H}\mathrm{o}}^{3+}$ moments form short-ranged ordered spin clusters. The internal field provided by the ordered $S=1\text{ }\text{ }{\mathrm{R}\mathrm{u}}^{4+}$ moments disrupts the fragile spin-ice state and drives the ${\mathrm{H}\mathrm{o}}^{3+}$ moments to order. We have directly measured a slight shift in the ${\mathrm{H}\mathrm{o}}^{3+}$ crystal field levels at 95 K from the Ru ordering.

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.
