利用多重散射理论，我们证明了由普通霍尔效应、异常霍尔效应和拓扑霍尔效应的线性叠加给出的具有天子的磁性系统中普遍接受的横向电阻率表达式是不完整的，必须用一个附加项“非共线”霍尔效应（NHE）来修正。它的角度形状是由磁性结构、电子的自旋轨道场和潜在的晶体结构决定的，这使我们能够将NHE从各种其他霍尔贡献中分离出来。它的大小与自旋轨道相互作用强度成正比。NHE是解码输运实验中二维和三维自旋织构所必需的基本术语。
Using multiple scattering theory, we show that the generally accepted expression of transverse resistivity in magnetic systems that host skyrmions, given by the linear superposition of the ordinary, the anomalous, and the topological Hall effect, is incomplete and must be amended by an additional term, the "noncollinear" Hall effect (NHE). Its angular form is determined by the magnetic texture, the spin-orbit field of the electrons, and the underlying crystal structure, allowing us to disentangle the NHE from the various other Hall contributions. Its magnitude is proportional to the spin-orbit interaction strength. The NHE is an essential term required for decoding two- and three-dimensional spin textures from transport experiments.
