在3 ~ 800 K的温度范围内，用穆斯堡尔效应测定了具有Sm，Gd，Tb，Dy，Ho和Th的RFe_3金属间化合物的易磁化方向。这些化合物的磁化强度是在基面内，除了SmFe 3，其中磁化强度平行于晶体学c轴。在HoFe_3中，在T = 100 K时观察到了磁相变。在T 100 K时，磁化平行于b轴。对于ThFe_3，发现了一个非常显著的磁性行为，在T = 140 K以下，ThFe_3是平行于a轴的铁磁有序。高于T = 295 K，磁化平行于b轴。在T = 140至295 K的温度范围内，ThFe 3几乎没有净磁化。
The easy direction of magnetization in RFe3 intermetallic compounds with R Sm, Gd, Tb, Dy, Ho, and Th is determined by means of the Mossbauer effect within a range of temperatures between 3 and 800 K. The magnetization of these compounds is within the basal plane with the exception of SmFe3, in which the magnetization is parallel to the crystallographic c-axis. In HoFe3 a magnetic phase transition is observed at T = 100 K. At T 100 K the magnetization is parallel to the b-axis. For ThFe3 a very remarkable magnetic behaviour is found. Below T = 140 K ThFe3 is ferromagnetically ordered parallel to the a-axis. Above T = 295 K the magnetization is parallel to the b-axis. In the temperature region from T = 140 to 295 K ThFe3 has practically no net magnetization.
