Abstract

fetched live from OpenAlex

We report the transport, thermodynamic, muon spin relaxation, and neutron study of the ${\mathrm{Ca}}_{0.74(1)}{\mathrm{La}}_{0.26(1)}$(${\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x}$)${\mathrm{As}}_{2}$ single crystals, mapping out the temperature-doping level phase diagram. Upon Co substitution on the Fe site, the structural and magnetic phase transitions in this 112 compound are suppressed and superconductivity up to 20 K occurs. Our measurements of the superconducting and magnetic volume fractions show that these two phases coexist microscopically in the underdoped region, in contrast to the related ${\mathrm{Ca}}_{10}$(${\mathrm{Pt}}_{3}{\mathrm{As}}_{8}$)((${\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Pt}}_{x}$)${}_{2}{\mathrm{As}}_{2}$)${}_{5}$ (10-3-8) compound, where coexistence is absent. Supported by model calculations, we discuss the differences in the phase diagrams of the 112 and 10-3-8 compounds in terms of the FeAs interlayer coupling, whose strength is affected by the character of the spacer layer, which is metallic in the 112 compound and insulating in the 10-3-8 compound.

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.
