Abstract

fetched live from OpenAlex

Magnetization configuration and magnetic switching of submiron “Pac-man” shaped Ni80Fe20 elements with conventional and modified (i.e., elongated) geometry have been studied using magnetic force microscopy, magneto-optical Kerr effect, and micromagnetic simulations. Experimental measurements and modeling analysis clearly demonstrate that the sensitive interplay between exchange, demagnetizing, and shape anisotropy energies leads to distinct magnetization configurations and magnetic switching mechanisms, even though the geometric shape of elements is only slightly modified. In a particular case, such as 40% elongated element, vortex-driven magnetic switching is replaced by well-defined coherent reversal.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
