Abstract

fetched live from OpenAlex

It is now well-established that the strong anisotropy in the magnetic properties of the intermetallic compounds UT 2 Si 2 , where T stands for a transition metal, is responsible for their rich magnetic phase diagram. However, within that series of compounds, UNi 2 Si 2 is one that shows an unusual sequence of magnetically ordered states. Thus, to better understand its unusual properties, we have investigated the elastic properties of UNi 2 Si 2 as a function of temperature, magnetic field, and pressure. In all three magnetic phases, our measurements indicate that the sound-velocity temperature dependence is dominated by the magnetoelastic coupling. Moreover, the analysis of the temperature dependence for the incommensurate longitudinal spin-density wave phase is consistent with a critical exponent β = 0.38 ± 0.01. We also present the magnetic phase diagram for UNi 2 Si 2 obtained at 0 and 8 kbar. Our investigation reveals that the triple-point coordinates (T p, H p ) decrease with pressure at a rate of dT p /dP = –0.1 K/kbar and dH p /dP = –0.1 T/kbar, respectively.

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.
