Abstract
We investigated magnetotransport properties, such as the clustering temperature ${T}^{\ensuremath{\ast}}$, ${T}_{C}$, magnetoresistance, and the resistivity of ${\text{Sm}}_{0.55}{\text{Sr}}_{0.45}{\text{MnO}}_{3}$ manganite (which exhibits a non-Curie-Weiss (CW) behavior, resulting from the multiphase competition and coexistence), and their evolution due to ruthenium doping on the Mn-ion site ($B$-site). These results have been compared with the predictions of a model of a system of two competing states in the presence of quenched disorder. Ru doping, which causes an interplay between the promotion of the long-range metallic ferromagnetic phase and the ${\text{Mn}}^{+3}{\text{-Mn}}^{+4}$ ions clustering, results in a suppression of the deviation from the Curie-Weiss law in $H/M(T)$, which is accompanied by an increase in ${T}_{C}$, a decrease in the resistivity and a reduction in the magnetoresistance. However ${T}^{\ensuremath{\ast}}$ is little affected by the doping.

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.
