Abstract
Magnetic phase transition in the manganite films has been found to be induced by the structural phase transition of the ${\text{SrTiO}}_{3}$ substrate at ${T}_{s}=105\text{ }\text{K}$ [Vlasko-Vlasov et al., Phys. Rev. Lett. 84, 2239 (2000) and Ziese et al., New J. Phys. 10, 063024 (2008)]. However, no change in the electrical transport properties has been detected at this temperature. Here we report the observation of the satellite peaks in the temperature dependence of the temperature coefficient of resistivity (TCR) at temperatures around 105 K in the ultrathin manganite films grown on ${\text{SrTiO}}_{3}$ substrates, triggered by the cubic-to-tetragonal structural phase transition in ${\text{SrTiO}}_{3}$. The TCR peak's magnitude decreases with an increasing thickness of the manganite film and with an increasing applied magnetic field. Our results demonstrate the strong coupling between the structural and transport properties in the manganite films.

How this classification was reachedexpand
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.
