利用Kubo公式推导了磁性多层膜的反常霍尔电阻率。结果表明，常用的非寻常霍尔电阻率与寻常电阻率之间的标度关系是不成立的。层平面内的霍尔电压和垂直于层平面的霍尔电压是完全不同的，就像这两种几何结构的普通介电常数不同一样。最近的实验结果进行了讨论，在这个配方。
The extraordinary Hall resistivity of magnetic multilayers is derived by using the Kubo formalism. It is found that the commonly used scaling relation between the extraordinary Hall resistivity and the ordinary resistivity is not valid. Hall voltages in the plane of the layers and perpendicular to the plane of the layers are quite different, just as the ordinary resistivities are different for these two geometries. Recent experimental results are discussed within this formulation.
