摘要：
通过热膨胀和磁致伸缩测量研究了DyRh$_2$Si$_2$和HoRh$_2$Si$_2$的单晶。在这些测量中可以清晰地看到不同类型的磁有序，特别是约12 K以下磁矩偏离晶体学$c$方向的倾斜，以及沿$c$方向施加磁场时的自旋翻转。对于HoRh$_2$Si$_2$，在$T_{\ m N}$以下不远处的一个额外转变通过Grüneisen比进行了分析，该转变很可能由磁结构的变化引起。我们的结果很好地佐证了这些材料上其他磁性和热力学测量的发现，并提供了进一步证据表明磁畴的形成。
英文摘要：
Single crystals of DyRh$_2$Si$_2$ and HoRh$_2$Si$_2$ were investigated by thermal expansion and magnetostriction. The different types of magnetic order can clearly be seen in these measurements, particularly the canting of the moments away from the crystallographic $c$ direction below about 12~K and the spin-flip for magnetic field applied along the $c$ direction. For HoRh$_2$Si$_2$, an additional transition just below $T_{\rm N}$ is analyzed by means of the Grüneisen ratio and is likely caused by a change of the magnetic structure. Our results nicely corroborate findings from other magnetic and thermodynamic measurements on these materials and provide further evidence suggesting the formation of magnetic domains.
