Formation of nanocrystalline films of Sr2FeMoO6 on Si(100) by pulsed laser deposition: Observation of preferential oriented growth
Bibliographic record
Abstract
Nanocrystalline Sr2FeMoO6 films have been grown on a Si(100) substrate by pulsed laser deposition under different growth conditions including deposition temperature and time. A nanocrystalline single-phase Sr2FeMoO6 film was obtained at a temperature as low as 600 °C. This high-quality ferromagnetic film was found to have a saturation magnetic moment of 3.4μB per formula unit and a coercive field of 1.5 kOe at 77 K with micrometer-sized magnetic domains. By using glancing-incidence x-ray diffraction with different incident beam angles, the crystal structure of the film was sampled as a function of depth. For the as-grown Sr2FeMoO6 films thicker than 60 nm, a preferential orientation of the nanocrystals in the film was observed, despite the lack of good lattice matching with the Si substrate. At a higher deposition temperature of 800 °C, the as-grown film exhibited the same saturation magnetic moment but with a discernibly lower coercive field of 0.8 kOe, consistent with the larger grain size obtained at a higher growth temperature.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
