Abstract
Multifunctional BiFeO3 (BFO), BiCrO3 (BCO), and BFO/BCO heteroepitaxial films with good ferroelectric properties were grown by pulsed laser deposition on epitaxial CaRuO3-coated (100)-oriented LaAlO3 and (LaAlO3)0.3(Sr2LaTaO6)0.7. The in-plane compressive strain induces a tetragonal crystal structure in both BFO and BCO films in the BFO/BCO bilayer, in contrast to their bulk counterparts. The small saturation magnetization observed at room temperature for the individual layers of BiFeO3 and BiCrO3 is significantly enhanced (twofold) in the bilayer heterostructures. We attribute this improvement to the superexchange magnetic interaction between Fe3+ and Cr3+, occurring at the interface, combined with the compressive strain.

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
