Abstract

fetched live from OpenAlex

In amorphous superconductors, superconducting and vortex-pinning properties are strongly linked to the absence of long-range order. Consequently, superconductivity and vortex phases can be studied to probe the underlying microstructure and order of the material. This is done here from resistance and local magnetization measurements in the superconducting state of ${\text{Fe}}_{x}{\text{Ni}}_{1\ensuremath{-}x}{\text{Zr}}_{2}$ metallic glasses with $0\ensuremath{\le}x\ensuremath{\le}0.6$. First, we present typical superconducting properties such as the critical temperature and fields and their dependence on Fe content in these alloys. Then, the observations of peculiar clockwise hysteresis loops, wide double-step transitions, and large magnetization fluctuations in glasses containing a large amount of Fe are analyzed to reveal a change in short-range order with Fe content. The results further shed light on our understanding of the interplay among superconducting coherence lengths, material microstructure, and pinning and how they can influence superconducting transitions in transport measurements.

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.
