Thermoelectric properties of hot‐pressed Ruddlesden‐Popper phases CaO(CaMnO <sub>3</sub> ) <i> <sub>m</sub> </i>
Bibliographic record
Abstract
Abstract We investigated the Ruddlesden‐Popper series CaO(CaMnO 3 ) m with m = 1, 2, 3, ∞, to study the impact of the varying amounts of CaO layers on their thermoelectric properties. Previous studies showed that highly dense samples are difficult to obtain due to the refractory nature of these materials. In this study, we managed to obtain dense pellets during a classical hot‐pressing step, if and only if the samples were subjected to extended ball‐milling prior to pressing, resulting in crystallite sizes of 30–35 nm after hot‐pressing. The sample with the largest amount of CaO layers ( m = 1) had the lowest electrical and thermal conductivity, and the highest Seebeck coefficient, as predicted. Ultimately the perovskite CaMnO 3 ( m = ∞ , no CaO layers) exhibited the best thermoelectric properties.

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.
