在非晶稀土（RE）过渡金属（TM）薄膜中测量了异常霍尔效应（EHE）和极性克尔效应（PKE）磁滞回线的温度依赖性。每个效应的极性对应于其TM分量的极性。霍尔电压的温度依赖性类似于克尔旋转角的温度依赖性，并且在Gd-Co-Mo膜中，它类似于由长谷川的二子晶格模型计算的Co子晶格矩的温度依赖性。从这些结果来看，RE-TM薄膜中的EHE和PKE都被认为主要与TM亚晶格矩有关。
The temperature dependences of the extraordinary Hall effect (EHE) and the polar Kerr effect (PKE) hysteresis loops are measured in amorphous rare‐earth (RE) transition metal (TM) films. The polarity of each effect corresponds to that of its TM component. The temperature dependence of Hall voltage is similar to that of the Kerr rotation angle, and, in Gd‐Co‐Mo films, it is similar to that of Co sublattice moment calculated by Hasegawa's two sublattice model. From these results, both EHE and PKE in RE‐TM films are considered to mainly associate with the TM sublattice moment.
