我们在高达 11 T 的磁场中对单晶 Ce 3 Pd 20 Si 6 进行了低至 90 mK 的磁化强度测量。在低磁场下，M (T) 中发现了两个转变；由于磁转变而在 0.27 K 处出现尖点，并且在大约 0.5 K 处向上弯曲，这可能对应于四极转变。发现后一个临界温度在磁场中强烈增强。 90 mK 处的磁化强度 M (H) 在 0.6 T 以上具有强烈的各向异性，并显示出与相变相关的几个明显特征。有趣的是，在低于 0.27 K 和 0.6 T 的磁相中没有发现明显的各向异性。
We have performed magnetization measurements of a single crystalline Ce 3 Pd 20 Si 6 down to 90 mK in fields up to 11 T. Two transitions were recognized in M (T) at low fields; a cusp at 0.27 K due to a magnetic transition, and an upward bending at~ 0.5 K that probably corresponds to a quadrupole transition. The latter critical temperature is found to be strongly enhanced in magnetic fields. The magnetization M (H) at 90 mK is strongly anisotropic above 0.6 T, and shows several sharp features associated with phase transitions. Interestingly, no appreciable anisotropy is found in the magnetic phase below 0.27 K and 0.6 T.
