Abstract
Abstract In room‐temperature hysteresis, 14 submicron hematites (0.12‐0.45 µm) had large coercive forces H c (150‐350 mT), while 22 natural 1‐5.5 mm hematite crystals had H c = 0.8‐23 mT (basal‐plane measurements). Single‐domain (SD) and multidomain (MD) hematites owe their high H c mainly to magnetoelastic anisotropy, caused in fine particles by internal strains and in large crystals by defects like dislocations, with a smaller contribution by triaxial magnetocrystalline anisotropy. A strong correlation between H c and the defect moment M d measured below hematite's Morin transition also favors magnetoelastic control. Saturation remanence/saturation magnetization ratios M rs / M s and coercivity ratios H cr / H c ( H cr is remanent coercive force) are distinctive: M rs / M s = 0.5‐0.9, H cr / H c = 1.02‐1.17 for MD hematites; M rs / M s = 0.5‐0.7, H cr / H c = 1.45‐1.62 for SD hematites. In high‐temperature (20‐690°C) hysteresis, H c ( T ) ~ M s ( T ) to a power 1.8‐2.4 above 385°C. Magnetoelastic wall pinning by crystal defects is thus more likely than control by domain nucleation which depends on magnetocrystalline anisotropy. Our results compare well with existing H c vs. crystal size d data. A suggested peak in H c around 15 µm and a proposed slope change around 100 µm are both questionable. Using only near‐saturation data, H c varies continuously as d −0.61 from ≈0.1 µm to 2 mm. The SD threshold size d 0 may be >15 µm but there is no strong evidence that d 0 ≈100 µm. Direct domain observations are needed to settle the question. Augmented data sets for H c and M rs vs. d show that SD hematite is increasingly affected by thermal fluctuations below ≈0.3 µm and generally confirm a superparamagnetic threshold size d s of 0.025‐0.03 µm.

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
