Abstract
Research on tuning the magnetic anisotropy of magnetic heterostructures has been receiving intensive attentions due to their intriguing tuning phenomena. In particular, tuning the magnetic anisotropy by in situ magnetic field during the fabrication process allows a remarkable control of magnetism with energy efficiency and shows significant potential applications for compact, fast, and low-power microwave and electronic devices. In this paper, in situ external out-of-plane and in-plane magnetic fields were applied during the deposition of Fe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> thin films on Pt substrates by atomic layer deposition at different temperatures (350 °C, 400 °C, and 450 °C). The effects of in situ magnetic field with different directions on the surface morphologies and magnetic properties of F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> /Pt heterostructures were characterized. It was found that both the out-of-plane and in-plane external magnetic fields tuned the magnetic anisotropy of ferromagnetic Fe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> O <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> when deposited at 400 °C with the maximum resonance field changes of 620 and 1930 Oe along in-plane and out-of-plane directions, respectively. This paper achieves tuning the magnetic properties through in situ magnetic field and provides a possibility for spintronic devices.

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.
