Bibliographic record
Abstract
Correlated electron phenomena in lanthanide and actinide materials are driven by a complex interplay between the $f$ and $d$ orbitals. In this study, aluminum $K$-edge x-ray absorption spectroscopy and density functional theory calculations are used to evaluate the electronic structure of the dialuminides, $M{\mathrm{Al}}_{2}$ ($M$ = Ce, Sm, Eu, Yb, Lu, U, and Pu). The results show how the energy and occupancy of the $4f$ or $5f$ orbitals impacts mixing of Al $3p$ character into the $5d$ or $6d$ conduction bands, which has implications for understanding the magnetic and structural properties of correlated electron systems.

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; both teacher heads agree on what is shown here.
