Abstract
This thesis compares the iron-based superconductors KFe2As2, RbFe2As2, and CsFe2As2 based on thermal expansion and magnetostriction measurements at temperatures between 50 mK and 4 K and in magnetic fields up to 14 T. The upper critical field is paramagnetically limited for magnetic fields applied parallel to the FeAs layers. Quantum oscillations of the magnetostriction yield extremal cross-sectional areas of the Fermi surface and effective quasiparticle masses, which are enhanced considerably.

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 it
