Abstract
We have used a combination of resonant magnetic x-ray scattering and x-ray absorption spectroscopy to investigate the properties of the doped spin-orbital Mott insulator ${\mathrm{Sr}}_{2}$${\mathrm{Ir}}_{1\ensuremath{-}x}$${\mathrm{Rh}}_{x}$O${}_{4}$ ($0.07\ensuremath{\le}x\ensuremath{\le}0.70$). We show that Sr${}_{2}$Ir${}_{1\ensuremath{-}x}$Rh${}_{x}$O${}_{4}$ represents a unique model system for the study of dilute magnetism in the presence of strong spin-orbit coupling, and provide evidence of a doping-induced change in magnetic structure and a suppression of magnetic order at ${x}_{c}\ensuremath{\sim}0.17$. We demonstrate that Rh-doping introduces Rh${}^{3+}$/Ir${}^{5+}$ ions which effectively hole-dope this material. We propose that the magnetic phase diagram for this material can be understood in terms of a novel spin-orbital percolation picture.

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
