Microwave study of the superconducting state of h<sub>8</sub>and d<sub>8</sub>κ-(BEDT-TTF)<sub>2</sub>Cu[ N(CN)<sub>2</sub>] Cl organic conductors
Bibliographic record
Abstract
At ambient pressure, the hydrogenated (h8) and deuterated (d8) κ-(BEDT-TTF) 2 Cu[N(CN) 2 ]Cl organic compounds are Mott insulators. Under a pressure of a few hundreds bars, an unconventional metallic state is induced and a superconducting one is observed below 13 K. In the insulating state, dc resistivity measurements have always indicated traces of superconductivity at low pressures (∼ 1 bar) although the most recent pressure-temperature phase diagrams are surprisingly silent on that issue. We have studied this unusual superconducting phase in both h8 and d8 single crystals by measuring the parallel and perpendicular microwave resistivities and dielectric constants as a function of temperature, pressure and magnetic field. For all pressure values, anomalies are always detected below 11 K; their behavior in a magnetic field is consistent with superconductivity.

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.
