Anomalous effect of doping on the superconducting state of CeCoIn<inf>5</inf>in high magnetic fields
Bibliographic record
Abstract
We investigated the effect of electron and hole doping on the high-field low-temperature superconducting state in CeCoIn 5 by measuring specific heat of CeCo (In 1-x M x ) 5 with M=Sn, Cd, and Hg and x up to 0.33% at temperatures down to 0.1 K and fields up to 14 T. Although both Cd and Hg doping (hole doping) suppresses the zero-field T c monotonically, H c2 increases with small amounts of doping and has a maximum around x=0.2% (M=Cd). On the other hand, with Sn doping (electron doping) both zero-field T c and H c2 decrease monotonically. The critical temperature for the high-field low-temperature superconducting state correlates with H c2 and T c , which we interpret in support of the superconducting origin of this state. © 2010 The American Physical Society.

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; a candidate call from one teacher head, not a consensus.
