在具有垂直磁各向异性的自旋阀Co/Pt/[Co/Pt] 2多层膜中，随着Pt间隔层厚度的增加，磁电阻、反常霍尔电阻率和纵向电阻率呈现振荡行为.此外，该参数随Pt间隔层厚度的变化而变化，而Pt间隔层厚度是通过拟合电阻率随温度变化的关系式（ρ xx 0为剩余电阻率，a′为斜散射参数，b由边跳和本征贡献组成）实验确定的。这些振荡行为主要归因于Pt间隔层的极化，而Co/Pt多层膜的极化则取决于Pt间隔层的厚度。
In the spin-valve Co/Pt/[Co/Pt]2multilayers with perpendicular magnetic anisotropy, it has been found that magnetoresistance, anomalous Hall resistivity, and longitudinal resistivity demonstrate oscillatory behaviors with the increase in Pt spacer thickness. Moreover, the parameterboscillates as a function of Pt spacer thickness, which is experimentally determined by fitting the equation(ρxx0is the residual resistivity,a′is the skew scattering parameter, andbconsists of the side jump and the intrinsic contributions) via the temperature dependence of the resistivity. These observed oscillatory behaviors can be mainly ascribed to the polarization of Pt spacer, while the polarization in the Co/Pt multilayers depends on the Pt spacer thickness.
