A coherent description of the anomalous Hall effect is presented that is applicable to pure and disordered systems. This is achieved by an implementation of the Kubo-Středa equation using the fully relativistic Korringa-Kohn-Rostoker method in combination with the coherent potential approximation. Applications to the pure ferromagnets Fe and Ni led to results in full accordance with previous work. For the alloy systems Fe(x)Pd(1-x) and Ni(x)Pd(1-x) very satisfying agreement with experiment could be achieved for the anomalous Hall conductivity. To interpret these results a detailed discussion of the skew and side-jump scattering processes is given.
本文提出了一种适用于纯净和无序系统的反常霍尔效应的连贯描述。这是通过使用完全相对论的 Korringa-Kohn-Rostoker 方法结合相干势近似来实现 Kubo-Středa 方程来实现的。对纯净的铁磁体 Fe 和 Ni 的应用得出的结果与以前的工作完全一致。对于合金系统 Fe(x)Pd(1-x)和 Ni(x)Pd(1-x)，可以非常满意地解释反常霍尔电导率的实验结果。为了解释这些结果，详细讨论了斜散射和侧跳散射过程。
