Abstract
Rare-earth-based permanent-magnet materials rich in iron have relatively low ferromagnetic ordering temperatures. This is believed to be due to the presence of antiferromagnetic exchange interactions, besides the ferromagnetic interactions responsible for the magnetic order. The magnetic properties of ${\mathrm{Ce}}_{2}{\mathrm{Fe}}_{17}$ are anomalous. Instead of ferromagnetic, it is antiferromagnetic, and instead of one ordering temperature, it shows two, at the N\'eel temperature ${T}_{N}\ensuremath{\sim}208\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ and at ${T}_{t}\ensuremath{\sim}124\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. ${\mathrm{Ce}}_{2}{\mathrm{Fe}}_{17}$, doped by 0.5% Ta, also shows two ordering temperatures, one to an antiferromagnetic phase, at ${T}_{N}\ensuremath{\sim}214\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, and one to a ferromagnetic phase, at ${T}_{0}\ensuremath{\sim}75\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. In order to clarify this behavior, single-crystalline samples were prepared by solution growth and characterized by electron microscopy, single-crystal x-ray diffraction, temperature-dependent specific heat, and magnetic field and temperature-dependent electrical resistivity and magnetization. From these measurements, magnetic $H\text{\ensuremath{-}}T$ phase diagrams were determined for both Ta-doped ${\mathrm{Ce}}_{2}{\mathrm{Fe}}_{17}$ and undoped ${\mathrm{Ce}}_{2}{\mathrm{Fe}}_{17}$. These phase diagrams can be very well described in terms of a theory that gives magnetic phase diagrams of systems with competing antiferro- and ferromagnetism.

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
