Electronic structure investigation of Mg<sub>1-<i>x</i> </sub>Fe<sub> <i>x</i> </sub>S solid solution: X-ray absorption study
Bibliographic record
Abstract
X-ray absorption fine structure at the sulfur K edge in Mg(1-x)Fe(x)S solid solution (0 < or = x < or = 0.68) has been measured at the Canadian Synchrotron Radiation Facility. It was shown that the S K-edge in MgS was formed by the multiple scattering of the photoelectron wave within a cluster of large size (containing 27 atoms and having radius about 4.5 A). Comparison of experimental data with theoretical results allows study of the electronic structure of this system. The analysis of partial electronic density of s-, p- and d- states makes it possible to investigate the mutual influence of sulfur s-, p- and metal d- states in the conduction band. The study of changes in experimental S K-edges XANES of Mg(1-x)Fe(x)S solid solution with variation of relative Fe-Mg concentration allows the extraction of the hypothetical cubic phase (B1) of FeS, and this is supported by theoretical simulation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
