Bibliographic record
Abstract
The control of magnetization using electric fields has been extensively studied in magnetoelectric multiferroic insulating materials while changes in magnetization in bulk metals caused by electric currents have attracted less attention. The recently discovered metallic magnet ${\mathrm{Ce}}_{3}{\mathrm{TiBi}}_{5}$ has been reported to exhibit current-induced magnetization. Here we determined the magnetic structure of ${\mathrm{Ce}}_{3}{\mathrm{TiBi}}_{5}$ using neutron diffraction, aiming to understand the microscopic origin of this magnetoelectric phenomenon in a metal. We established that the antiferromagnetic order emerging below ${T}_{N}=5\phantom{\rule{0.28em}{0ex}}\mathrm{K}$ is a cycloid order described by $P{6}_{3}/mcm.{1}^{\ensuremath{'}}(0,0,g)00sss$ with small moment sizes of $0.50(2)\phantom{\rule{0.28em}{0ex}}{\ensuremath{\mu}}_{B}$ and propagation vector $\mathbf{k}=(0,0,0.386)$. Surprisingly, the symmetry of this magnetic structure is inconsistent with the presence of current-induced magnetization and potential origins of this inconsistency with previous results are discussed. Additionally, our results suggest that moments order along their hard magnetic direction in ${\mathrm{Ce}}_{3}{\mathrm{TiBi}}_{5}$, a phenomenon which has been observed in other Kondo systems.

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; both teacher heads agree on what is shown here.
