在本文中，我们报告了与 [Co/Pd1−xAgx]n 多层膜中的磁阻行为相关的反常霍尔效应 (AHE)。对于n = 6的多层膜，Ag含量从x = 0增加到0.52导致AHE符号从负表面散射主导的AHE转变为正界面散射主导的AHE，这伴随着从各向异性磁阻（AMR）主导输运到巨磁阻（GMR）主导输运的转变。对于 n = 80，使用 Rs∝ρxxγ 进行标度分析，x = 0.52 时得出 γ ∼ 3.44，表示 GMR 型传输，而 x = 0 时得出 γ ∼ 5.7，表示 AMR 型传输。
In this paper, we report anomalous Hall effect (AHE) correlated with the magnetoresistance behavior in [Co/Pd1−xAgx]n multilayers. For the multilayers with n = 6, the increase in Ag content from x = 0 to 0.52 induces the change in AHE sign from negative surface scattering-dominated AHE to positive interface scattering-dominated AHE, which is accompanied with the transition from anisotropy magnetoresistance (AMR) dominated transport to giant magnetoresistance (GMR) dominated transport. For n = 80, scaling analysis with Rs∝ρxxγ yields γ ∼ 3.44 for x = 0.52 which presents GMR-type transport, in contrast to γ ∼ 5.7 for x = 0 which presents AMR-type transport.
