Abstract

fetched live from OpenAlex

The effect of Co content on the phase formation, structure, and magnetocaloric effect of rapidly quenched La(Fe1−xCox)11.4Si1.6 with x=0 to 0.12 were investigated by x-ray diffractometry and magnetic measurements. Rietveld analyses indicate that with increasing Co content, the amount of the 1:13 phase increases from about 22 to 62 wt. % in the rapidly quenched alloys. A very short time annealing (1273K∕20min) of the as-quenched alloy is sufficient for the formation of a single phase 1:13 structure. The peak value of the magnetic entropy change is 20.5,11.8,9.9J∕kgK for the annealed rapidly quenched compounds with x=0, 0.04, and 0.08, respectively. Increasing Co content drives the order of magnetic transition, near TC, from first order to second order and eliminates the occurrence of the field-induced magnetic transition above TC, which is responsible for the decrease in the magnetocaloric effect.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
