Abstract
Nearly nanometer-thick cuprates are an appealing platform for devices as well as exploring the roles of dimensionality, disorder, and free carrier density in these compounds. To this end we have produced exfoliated crystals of ${\text{Bi}}_{2}{\text{Sr}}_{2}{\text{Dy}}_{x}{\text{Ca}}_{1\ensuremath{-}x}{\text{Cu}}_{2}{\text{O}}_{8+\ensuremath{\delta}}$ on oxidized silicon substrates. The exfoliated crystals were characterized via atomic force and polarized Raman microscopies. Proper procedures for production, handling, and monitoring of these thin oxides are described. We observe a significant change in the effective exchange constant $J$ of these exfoliated crystals.
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.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
