Abstract

fetched live from OpenAlex

Abstract In this study, the structural and magnetic properties of exchange coupled nanocomposite FePt‐FePt 3 films were investigated. X‐ray diffraction and transmission electron microscopy results showed that after rapid thermal annealing (600 °C for 6 minutes), a phase transformation from [Pt+Fe] into composite FePt‐FePt 3 phases was obtained. Annealing created an ordered FePt phase that resulted in a large room temperature coercivity (H c ∼ 3200 Oe) compared to the as‐deposited film (H c ∼ 20 Oe). While no exchange bias field (H ex ∼ 0 Oe) was measured at room temperature, the annealed sample showed significant H ex ∼ ‐500 Oe at lower temperatures (150 K ≤ T ≤ 250 K), indicative of exchange coupling between FePt and FePt 3 . The high blocking temperature (∼250 K) indicates FePt 3 exhibits an enhanced Néel temperature. Further increasing the annealing temperature to 700 °C resulted in a reduction of H ex which is attributed to the transformation of FePt 3 into the FePt phase at this higher annealing temperature.

Teacher imitation

Not 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.
