我们报道了在高达58℃的静磁场和脉冲磁场中的磁性和弹性性质。从超声结果中，我们得到了在2℃时与磁有序有关的相变的证据。此外，在顺磁状态下，随着温度和磁场的变化，磁化强度和弹性模数出现了显著的反常。我们使用包含四极相互作用的晶体-电场(CEF)模型解释了我们的发现，并提出了这种材料的CEF能级方案。然而，CEF效应不能解释所有的场诱导异常，这表明需要改进的模型来解释这些。
We report on the magnetic and elastic properties ofin static and pulsed magnetic fields up to 58 T. From the ultrasound results, we obtain evidence for a phase transition at 2 K related to magnetic ordering. Furthermore, in the paramagnetic state,shows pronounced anomalies in the magnetization and elastic moduli as a function of temperature and magnetic field. We explain our findings using a crystal-electric-field (CEF) model that includes quadrupolar interactions and propose a CEF level scheme for this material. However, the CEF effects cannot explain all field-induced anomalies, which indicates that refined models are needed for explaining these.
