在 1.40°K 至 290°K 的温度范围内测量了一些镍盐的顺磁化率。在NiCl 2 ·6H 2 O中，磁化率与温度曲线在最低温度区的平坦行为尤其突出。采用低场近似计算了镍盐粉末样品的顺磁化率。镍离子在各种盐中的特征行为被解释为由于最低自旋三重态的斯塔克分裂。对磁敏度的测量值进行了分析，得到了一致的结果。特别是在NiCl 2 ·6H 2 O中，晶体场预计会从立方对称性发生很大的变形，这与在该盐中在9800和18000Mc/sec下无法检测到顺磁共振的事实是一致的。
Paramagnetic susceptibilities of some nickel salts were measured in the temperature range between 1.40°K and 290°K. The flat behavior of the susceptibility v s temperature curve in the lowest temperature region was especially prominent in NiCl 2 ·6H 2 O. The paramagnetic susceptibility of a powdered specimen of the nickel salt was calculated with the low field approximation. The characteristic behavior of a nickel ion in various salts was explained as due to the Stark splitting of the lowest spin triplet. The measured values of susceptibility were analysed and consistent results were obtained. Especially in NiCl 2 ·6H 2 O, the crystalline field was expected to be much deformed from cubic symmetry and this is consistent with the fact that the paramagnetic resonance could not be detected at 9800 and 18000 Mc/sec in this salt.
