在4.2 ~ 150 K的低场交流磁化率下，测量了铒单晶在不同频率和磁场下的磁化率，并测量了平行和垂直于c轴的磁场。磁化率的真实的分量在反铁磁转变（TN=85 K）和铁磁转变（TC=19 K）以及基面有序转变（52 K）和相称转变（34和28 K）处显示异常。在这些转变的磁效应进行了讨论，在同一晶体上以前的量热测量的结果。为了解释所观察到的非零值的虚部的磁化率在过渡，不同的损失机制的建议。
The magnetic properties of monocrystalline erbium have been determined with low-field AC susceptibility measurements between 4.2 and 150 K for different frequencies and magnetic fields with the applied field parallel and perpendicular to the c axis. The real component of the susceptibility shows anomalies at the antiferromagnetic transition (TN=85 K) and at the ferromagnetic transition (TC=19 K) as well as for the basal plane ordering transition at 52 K and for commensurate transitions at 34 and 28 K. The magnetic effects at these transitions are discussed in relation to the results of previous calorimetric measurements on the same crystal. To account for the observed non-zero value of the imaginary part of the susceptibility at the transitions, different loss mechanisms are suggested.
