Strong unidirectional anisotropy in spin-density-wave (Cr+6.5%Co)1−xVx alloys
Bibliographic record
Abstract
The magnetization, M(T), and magnetic susceptibility, χ(T) = M(T)/H, of the (Cr+6.5% Co)1−xVx (0⩽×⩽5% V) spin-density-wave (SDW) alloy system, have been measured in the presence of a magnetic field, H=100 Oe–5 T, in the field-cooled and zero field-cooled states, over the temperature range, 2⩽T⩽400 K. The thermal hysteresis corresponds to an irreversibility temperature Ti above the Néel temperature TN. M(H) measured at T=2 K in the FC (H=5 T) state exhibits magnetic hysteresis corresponding to a strong unidirectional anisotropy. The remanent magnetization MRem(T) decreases rapidly with increasing temperature, disappearing at Ti. The behavior is explained in terms of spin frustration of Cr moments close to the Co impurity atoms, with a component also due to Co clusters, whose moments are frozen in the SDW phase.

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.
