在1.7-91 °K和1.6-79 °K范围内分别测量了粉末状二甲基氯化铵铜（II）（DMACuCl 3）和四甲基氯化铵镍（II）（TMANiCl 3）的初始结晶度。DMACuCl 3在低于10 °K时表现出与Curie-韦斯行为的偏差。这些偏差与基于线性反铁磁相互作用的模型并不矛盾。为了拟合这些偏差，使用了8个模型。在居里-韦斯区，数据与关系式χM=C/（T+θ）− α的最小二乘拟合得到以下值：C=0.437（0.006），θ=0.317（0.278），α=−0.00014（0.00007）。TMANiCl 3在低于30 °K时表现出与Curie-韦斯行为的偏差，这与线性铁磁相互作用并不矛盾。使用两个一维模型来拟合这些偏差。在居里-韦斯区，用最小二乘拟合关系式χM=C/（T+θ）− α得到以下值：C=1.28（0.34），θ=−4.80（5.25），α=0.00010（0.00379）。两者之间的区别…
The initial susceptibilities of powder dimethylammonium copper (II) chloride (DMACuCl3) and tetramethylammonium nickel (II) chloride (TMANiCl3) have been measured in the ranges 1.7–91 °K and 1.6–79 °K, respectively. DMACuCl3 exhibited deviations from Curie‐Weiss behavior below 10 °K. The deviations were not inconsistent with models based on linear antiferromagnetic interactions. Eight models were used in an attempt to fit these deviations. A least‐squares fit of the data to the relation χM=C/(T+θ) − α in the Curie‐Weiss region yielded the following values: C=0.437 (0.006), θ=0.317 (0.278), and α=−0.00014 (0.00007). TMANiCl3 exhibited deviations from Curie‐Weiss behavior below 30 °K which were not inconsistent with linear ferromagnetic interactions. Two one‐dimensional models were used to fit these deviations. A least‐squares fit of the data to the relation χM=C/(T+θ) − α in the Curie‐Weiss region yielded the following values: C=1.28 (0.34), θ=−4.80 (5.25), and α=0.00010 (0.00379).
