Infrared active phonons in SrRu<sub><i>x</i></sub>O<sub>3</sub>and SrRu<sub><i>x</i></sub>Mg<sub>1−<i>x</i></sub>O<sub>3</sub>thin films
Bibliographic record
Abstract
Infrared reflectance measurements (100?5000?cm?1) were performed on well characterized thin films of SrRuxMg1?xO3 and SrRuxO3 fabricated on [0?0?1] oriented SrTiO3 single crystal substrates using pulsed laser deposition. In the films, which were less than 300?nm thick and some of which were insulating, the reflectance data show structure due to both the films and the substrate. Kramers?Kronig constrained variational dielectric fitting was employed to extract the real optical conductivities. Only a small number of infrared active modes appear in the reflectance spectra compared with the number allowed by orthorhombic symmetry in shell model calculations. The infrared signature for replacement of Ru by Mg in SrRuO3 is a mode near 655?cm?1.

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.
