Depth dependence of itinerant character in Mn-substituted Sr<sub>3</sub>Ru<sub>2</sub>O<sub>7</sub>
Bibliographic record
Abstract
We present a core-level photoemission study of Sr(3)(Ru(1-x)Mn(x))(2)O(7), in which we monitor the evolution of the Ru-3d fine structure versus Mn substitution and probing depth. In both Ru-3d(3/2) and -3d(5/2) core levels, we observe a clear suppression of the metallic features, i.e. the screened peaks, implying a sharp transition from itinerant to localized character already at low Mn concentrations. A comparison of soft and hard x-ray photoemission, which enables tunable depth sensitivity, reveals that the degree of localized/metallic character for Ru at the surface is different from that in the bulk.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
