Abstract
The effect of Ti doping in Bi 0.3 Ca 0.7 Mn 1− x Ti x O 3 (where x = 0.0, 0.015, 0.03, 0.05, 0.08, 0.12 and 0.16) on structural, magnetic and transport properties have been studied. The charge-ordering temperature ( T CO ) decreases gradually with increasing Ti doping content, and finally disappears completely for x = 0.12. The Neel temperature ( T N ) also decreases with increasing Ti doping content. A transition to a cluster glass like state is observed at T ⩽ T N . The zero field cooled/field cooled (ZFC/FC) magnetization decreases at high temperature ( T > 200 K) with increasing Ti content, whereas an opposite trend is observed at low temperature ( T < 200 K). Small exchange bias effect is also observed for x = 0.08 at 10 K. The resistivity increases with increasing Ti doping content. The disorder induced by Ti doping on the Mn site plays a key role in explaining the observed magnetic and electrical properties.

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 it
