TL;DR
This study investigates how applying high pressure affects the ferromagnetic properties of LaCrSb$_3$, revealing a gradual suppression of ferromagnetism and Cr-moment reduction, aligning with theoretical models but showing smoother transitions.
Contribution
It provides comprehensive experimental data on pressure effects on LaCrSb$_3$, highlighting the gradual suppression of ferromagnetism and validating theoretical predictions with some deviations.
Findings
Ferromagnetism fully suppressed at 26.5 GPa
Cr-moment decreases steadily with pressure
Unit cell volume decreases smoothly up to 55 GPa
Abstract
We have performed an extensive pressure-dependent structural, spectroscopic, and electrical transport study of LaCrSb. The ferromagnetic phase (T = 120 K at p = 0 GPa) is fully suppressed by p = 26.5 GPa and the Cr-moment decreases steadily with increasing pressure. The unit cell volume decreases smoothly up to p = 55 GPa. We find that the bulk modulus and suppression of the magnetism are in good agreement with theoretical predictions, but the Cr-moment decreases smoothly with pressure, in contrast to steplike drops predicted by theory. The ferromagnetic ordering temperature appears to be driven by the Cr-moment.
