Abstract

fetched live from OpenAlex

Correlation between the nanoscopic disorder in the nanostructures in the a-b planes of high Tc superconductors and the macroscopic properties has been studied. It has been found that nanostructures govern the temperature dependence of the transport and magnetic properties such as: the critical current density Jc(T), the superfluid density ns(T)varies direct as1/(lambda) ab2(T) and the normalized magnetic relaxation rate S(T). They also determine magnetic flux pinning: the dependence of the energy barrier on the current density Ueff(J). Irradiation with heavy ions affects the above properties through the change of the disorder in the nanostructure array. The studies have been performed on YBCO and TlBCCO thin films.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
