Oxygen-isotope exchange and cation disorder effects on magneto-transport properties of (Sm1-yGdy)0.55Sr0.45MnO3
Bibliographic record
Abstract
Detailed systematic studies of the effects of both the cation disorder and the oxygen isotope exchange 16O → 18O on the magneto-transport properties of (Sm1-yGdy)0.55Sr0.45MnO3 manganites were performed for y between 0 and 1. We investigated changes in the temperature and magnetic field dependence of the magnetization, resistivity and magneto-resistivity, including the effects of the oxygen isotope substitution on the magneto-transport properties of samples with high magneto-resistance and the oxygen-isotope exchange induced metal–insulator transition. Very large cation disorder leads to a formation of the insulating spin-glass state in which no colossal magneto-resistance or field-induced ferromagnetism occurs. There is also no significant effect of the oxygen isotope exchange on samples in the spin-glass state.

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.
