我们推导出一个一般的标度关系的异常霍尔效应在铁磁金属中涉及多个竞争的散射机制，描述了一个二次超曲面的空间中跨越的偏磁率。我们还提出了实验结果，这表明强烈偏离以前发现的缩放形式时，不同的散射机制竞争的强度，但可以很好地解释我们的理论。
We derive a general scaling relation for the anomalous Hall effect in ferromagnetic metals involving multiple competing scattering mechanisms, described by a quadratic hypersurface in the space spanned by the partial resistivities. We also present experimental findings, which show strong deviation from previously found scaling forms when different scattering mechanisms compete in strength but can be nicely explained by our theory.
