Surface inhomogeneities and the electronic phase separated states in thin films of La0.35Pr0.35Ca0.3MnO3
Bibliographic record
Abstract
We have studied the effects of film thickness and surface inhomogeneities on the fluid and static phase separated states of La0.35Pr0.35Ca0.3MnO3 films grown on LaAlO3 and SrTiO3 substrates which provide compressive and tensile strain, respectively. The shapes and areas of the resistance versus magnetic field hysteresis loops were used to identify the type of phase separated state in the films. Atomic force microscopy revealed an increase of the relative surface roughness of the films with a decreasing thickness. The resultant distribution of the strain produces a dramatic enhancement of the inhomogeneous electronic phase separation as well as large changes in the dependence of the resistivity on magnetic field in the thinnest films deposited on both types of substrates. In contrast to thick films, the static phase separated state in the thinnest films is more inhomogeneous than the fluid phase separated one.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
