对亚锡矿的合成类似物 Cu2FeSnS4 进行磁化测量，以表征低温下的反铁磁转变，Bernardini 等人证明了这一点。 （2000）。通过静态磁化测量检查材料的温度和磁场依赖性，扫描高达 12 T 的磁场和 1.4-20 K 范围内的温度，同时在 1.8 至 510 Hz 范围内的不同频率下收集交流磁化率数据。在尼尔温度 6.1(2) K 之上和之下进行的静态和动态磁化数据均证实了锡矿在长程范围内具有反铁磁性。此外，还观察到相对于 Mn 类似物，磁各向异性和交换相互作用均有所增加（Fries 等人，1997）。
Magnetisation measurements were performed on the synthetic analogue of stannite, Cu2FeSnS4, in order to characterise the antiferromagnetic transition at low temperature, evidenced by Bernardini et al. (2000). Temperature and field dependence of the material were checked by means of static magnetisation measurements, carried out scanning the magnetic fields up to 12 T and temperatures in the range 1.4-20 K, while ac susceptibility data were collected at different frequencies ranging from 1.8 to 510 Hz. Both static and dynamic magnetisation data, performed above and below the Neel temperature, 6.1(2) K, confirm stannite to order antiferromagnetically at a long-range scale. Moreover, an increase of both the magnetic anisotropy and the exchange interaction, with respect to the Mn-analogue (Fries et al. 1997), has been observed.
