Abstract

fetched live from OpenAlex

The synthesis and characterization of ${\mathrm{Ba}}_{3}{\mathrm{CuSb}}_{2}{\mathrm{O}}_{9}$, which has a layered array of ${\mathrm{Cu}}^{2+}$ spins in a triangular lattice, are reported. The magnetic susceptibility and neutron scattering experiments of this material show no magnetic ordering down to 0.2 K with a ${\ensuremath{\theta}}_{\mathrm{CW}}=\ensuremath{-}55\text{ }\text{ }\mathrm{K}$. The magnetic specific heat reveals a $T$-linear dependence with a $\ensuremath{\gamma}=43.4\text{ }\text{ }\mathrm{mJ}\text{ }{\mathrm{K}}^{\ensuremath{-}2\text{ }}\text{ }{\mathrm{mol}}^{\ensuremath{-}1}$ below 1.4 K. These observations suggest that ${\mathrm{Ba}}_{3}{\mathrm{CuSb}}_{2}{\mathrm{O}}_{9}$ is a new quantum spin liquid candidate with a $S=1/2$ triangular lattice.

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.
