本文基于Kubo线性响应理论，研究了典型铁磁过渡金属合金系统fcch的电磁输运和热电磁输运。全电导率张量的结果允许讨论自旋-轨道诱导的各向异性磁电阻和反常霍尔效应。这些是补充相应的热电磁输运性质的Seebeck效应和异常能斯特效应的各向异性的结果。相应的响应系数之间的关系进行了讨论与底层的电子结构计算相对论内的Korringa-Kohn-Rostoker相干势近似带结构方法无序合金。
The galvanomagnetic and thermogalvanomagnetic transport of the prototypical ferromagnetic transition-metal alloy system fcchas been investigated on the basis of Kubo's linear response formalism. The results for the full electric conductivity tensor allow discussing the spin-orbit-induced anisotropic magnetoresistance and the anomalous Hall effect. These are complemented by results for the corresponding thermogalvanomagnetic transport properties anisotropy of the Seebeck effect and anomalous Nernst effect. The relation between the respective response coefficients is discussed with the underlying electronic structure calculated relativistically within the Korringa-Kohn-Rostoker coherent potential approximation band structure method for disordered alloys.
