论文摘要
我们进行了广泛的依赖压力的结构,光谱和电气传输研究,对LACRSB $ _3 $。铁磁相(p = 0 GPA时T $ _C $ = 120 K)被p = 26.5 GPA完全抑制,并且随着压力的增加,CR仪稳定下降。单位细胞体积平滑降至P = 55 GPA。我们发现,磁性的批量模量和抑制与理论预测非常吻合,但是与理论预测的类似的类似的滴滴相反,CR刺激随着压力而平稳地降低。铁磁有序温度似乎是由Cr量驱动的。
We have performed an extensive pressure-dependent structural, spectroscopic, and electrical transport study of LaCrSb$_3$. The ferromagnetic phase (T$_C$ = 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.
