Metal–insulator transition in Mg-doped SrRuO<sub>3</sub>thin films prepared by laser ablation
Bibliographic record
Abstract
Thin films of magnesium doped SrRuO3 (Mg-SRO) have been successfully prepared by laser ablation on SrTiO3 (100) substrates. The stoichiometry, structural, electrical and magnetic properties of the films depend on the substrate temperature (Ts) and oxygen pressure ( ) during deposition. All Mg-SRO films are ferromagnetic, but the transport properties and remanent moments vary with Ts and . Metallic films are produced for Ts ⩾ 700 °C whereas insulating films can be produced with Ts = 500 °C with . A correlation between lattice parameter, stoichiometry and transport properties has been discovered: the larger lattice parameter correlates with the decreased Ru content and more insulating samples. Insulating samples prepared at Ts = 500 °C and have stoichiometry close to the SrMg0.15Ru0.85O3 and are ferromagnetic Anderson insulators with transport properties consistent with variable range hopping.

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.
