We present measurements of the anisotropic magnetoresistance (AMR) of La(0.75)Sr(0.25)MnO(3) films deposited on (001) SrTiO(3) substrates, and a model that describes the experimental results. The model, based on the electronic structure of manganites plus the spin-orbit coupling, correctly accounts for the dependence of the AMR on the direction of the current to the crystalline axes. We measure an AMR of the order of 10(-3) for the current I parallel to the [100] axis of the crystal and vanishing AMR for I
我们展示了 La(0.75)Sr(0.25)MnO(3) 薄膜在 (001) SrTiO(3) 衬底上的各向异性磁阻 (AMR) 的测量结果，以及一个描述实验结果的模型。该模型基于锰氧化物的电子结构和自旋轨道耦合，正确地解释了 AMR 对电流方向相对于晶体轴的依赖性。我们测量到电流 I 平行于晶体的[100]轴时的 AMR 约为 10(-3)，而 I
