Abstract

fetched live from OpenAlex

The high-field superconducting state in ${\mathrm{CeCoIn}}_{5}$ has been studied by transverse field muon spin rotation measurements with an applied field parallel to the crystallographic $c$ axis close to the upper critical field ${\ensuremath{\mu}}_{0}{H}_{c2}=4.97\text{ }\text{ }\mathrm{T}$. At magnetic fields ${\ensuremath{\mu}}_{0}H\ensuremath{\ge}4.8\text{ }\text{ }\mathrm{T}$ the muon Knight shift is enhanced and the superconducting transition changes from second order towards first order as predicted for Pauli-limited superconductors. The field and temperature dependence of the transverse muon spin relaxation rate $\ensuremath{\sigma}$ reveal paramagnetic spin fluctuations in the field regime from $2\text{ }\text{ }\mathrm{T}\ensuremath{\le}{\ensuremath{\mu}}_{0}H&lt;4.8\text{ }\text{ }\mathrm{T}$. In the normal state close to ${H}_{c2}$ correlated spin fluctuations as described by the self-consistent renormalization theory are observed. The results support the formation of a mode-coupled superconducting and antiferromagnetically ordered phase in ${\mathrm{CeCoIn}}_{5}$ for $H$ directed parallel to the $c$ axis.

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.
