Abstract
Magnetic properties and magnetocaloric effect (MCE) in Co rich Er(Co1−xFex)2 have been studied by magnetic measurements and electronic structure calculations. With increasing x from 0 to 0.2, TC increases from 32to360K and the magnetization decreases from 6.8μB to 5.3μB per formula unit (5K), respectively. The peak value of the magnetic entropy change decreases rapidly from 23.0to4.5J∕kgK (under an external field change of 5T) with increasing x from 0 to 0.1. The addition of a small amount of Fe in ErCo2 drives the order of magnetic transition from first order to second order, as evidenced by the magnetothermal curves around TC, which is responsible for the decrease in MCE. The magnetic moment dependence of total energy Et(m) is studied by a fixed spin moment band structure calculation. Et(m) for x=0 has two minima at a low and a high Co magnetic moment, which correspond to a metastable and a stable magnetic state, respectively. On the other hand, Et(m) for x=0.125 shows only one minimum at a high Co (Fe) magnetic moment. These fixed spin moment calculation results explain the observed change in the order of magnetic transition by the addition of Fe in ErCo2.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
