Abstract
${\text{LiZn}}_{2}{\text{Mo}}_{3}{\text{O}}_{8}$ has been proposed to contain $S=\textonehalf{}$${\text{Mo}}_{3}{\text{O}}_{13}$ magnetic clusters arranged on a triangular lattice with antiferromagnetic nearest-neighbor interactions. Here, microwave and terahertz electron spin resonance, $^{7}\mathrm{Li}$ nuclear magnetic resonance, and muon spin rotation spectroscopies are used to characterize the local magnetic properties of ${\text{LiZn}}_{2}{\text{Mo}}_{3}{\text{O}}_{8}$. These results show the magnetism in ${\text{LiZn}}_{2}{\text{Mo}}_{3}{\text{O}}_{8}$ arises from a single isotropic $S=\textonehalf{}$electron per cluster and that there is no static long-range magnetic ordering down to $T$ = 0.07 K. Further, there is evidence of gapless spin excitations with spin fluctuations slowing down as the temperature is lowered. These data indicate strong spin correlations, which, together with previous data, suggest a low-temperature resonating valence-bond state in ${\text{LiZn}}_{2}{\text{Mo}}_{3}{\text{O}}_{8}$.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
