Pressure induced phase transition in periodic microtwinned thin film of La0.88Sr0.1MnO3
Bibliographic record
Abstract
We have studied the resistivity of a hole-doped 95nm thin film of La0.88Sr0.1MnO3 sample as a function of pressure up to 2.0GPa. For pressures below 0.81GPa, the sample showed that the resistivity decreased at all temperatures and the metal insulator transition temperature TMI increased to higher temperatures similar to the pressure results observed previously in bulk samples and thin films of manganites. However, for pressures above 0.81GPa, we observed a rapid increase in resistivity and a rapid decrease of TMI as a function of pressure. The rate of change of TMI with pressure is −133.5K∕GPa which is an order of magnitude larger than that of bulk samples and thin films of manganite with an opposite sign. We interpreted our results as a consequence of a phase change in the film by pressure from having strain induced periodic microtwinned regions below 0.81GPa to a strained free region and formation of coherent twins above this pressure in 95nm thin film of La0.88Sr0.1MnO3.

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.
