Abstract

fetched live from OpenAlex

We have performed measurements of the critical neutron scattering on ${\mathrm{C}\mathrm{s}\mathrm{C}\mathrm{o}}_{0.83}{\mathrm{M}\mathrm{g}}_{0.17}{\mathrm{B}\mathrm{r}}_{3}$, a dilute stacked triangular lattice (STL) Ising antiferromagnet (AF). A two component line shape associated with the critical fluctuations appears at a temperature coincident with ${T}_{N1}$ observed in pure ${\mathrm{C}\mathrm{s}\mathrm{C}\mathrm{o}\mathrm{B}\mathrm{r}}_{3}$. Such scattering is indicative of fluctuations in prototypical random field Ising model (RFIM) systems. The random field domain state arises in this case due to geometrical frustration within the STL Ising AF, which gives rise to a three sublattice N\'eel state, in which one sublattice is disordered. Magnetic vacancies nucleate AF domains in which the vacancies reside on the disordered sublattice thereby generating a RFIM state in the absence of an applied magnetic field.

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.
