Abstract
Zero-field and in field electrical resistivity, magnetoresistivity, and magnetization measurements have been performed in the temperature range of 4.2 K to 300 K and in the fields up to 60 kOe on amorphous ${\mathrm{Fe}}_{90\ensuremath{-}x}{\mathrm{Mn}}_{x}{\mathrm{Zr}}_{10}(0<~x<~16)$ alloys. Unusual properties such as a broad resistivity minimum in the higher-temperature region and a resistivity minimum close to Curie temperature were observed for alloys with a certain Mn content. An analysis of the resistivity data using existing theories reveals the actual functional dependencies of resistivity on temperature in different temperature ranges. The enhancement of spin fluctuation with Mn concentration has been observed from resistivity data and is further supported by the magnetization data. A comparative study of magnetic and transport properties indicates that remarkable effects due to magnetic ordering are present in both resistivity and magnetoresistivity. The observed composition dependence of the spontaneous resistive anisotropy is explained in terms of the two-current-conduction model. The determined values of composition dependence of spin-up and spin-down residual resistivity provide conclusive evidence of weak itinerant ferromagnetism over the entire composition range of the present investigation. These results are further supported by the high-field dc susceptibility data obtained from magnetization measurements.

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; both teacher heads agree on what is shown here.
