Abstract

fetched live from OpenAlex

Abstract We have investigated the structures and magnetic properties of as‐deposited and annealed [Pt(20 Å)/Fe(15 Å)] 10 /Pt(30 nm) multilayers under different End‐Hall voltages (V EH = 0 ∼ 150 V). The films deposited with no End‐Hall voltage consisted of Fe (a = 2.91 Å), Pt (3.96 Å), and disordered FePt (a = 3.82 Å) phases. Increasing V EH helps compact the individual Fe and Pt layers, while preventing FePt intermixing. However, increasing the annealing temperature to 550 °C resulted in an ordered f.c.t. FePt (a = 3.85 Å, c = 3.73 Å) phase for films deposited with V EH = 0V, and a mixture of Fe and Pt phases with grain coarsening was found for films prepared with V EH = 150 V. A drastic increase in coercivity (H c ∼ 4600 Oe) in the annealed sample (V EH = 0 V) is attributed to the formation of FePt phases. A decrease in H c with increasing V EH indicates that FePt formation may be suppressed via more energetic ion beam bombardment that resulted in the activation barrier of diffusion increasing dramatically.

Full frame distilled prediction

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.
