本简要报告展示了与没有 Ru 间隔物的 ML 相比，Ru 介导的反铁磁耦合 [Pt/Co]5/Ru/[Co/Pt]5 多层 (ML) 中巨大的非凡霍尔效应 (EHE)。 EHE 的增强归因于强烈的 Ru/Co 界面散射。通过Pt层厚度和温度的变化，我们确定了霍尔电压和纵向电阻率之间的关系。人们发现，传统的标度分析很难一致地解释我们的数据。
This Brief Report presents giant extraordinary Hall effect (EHE) in the Ru-mediated antiferromagnetically coupled [Pt/Co]5/Ru/[Co/Pt]5 multilayers (MLs) compared with those MLs without the Ru spacer. The enhancement of the EHE is attributed to the strong Ru/Co interface scattering. Through the variation in the Pt layer thickness and the temperature, we determine the relation between the Hall voltage and the longitudinal resistivity. It is found that the conventional scaling analysis has difficulties in consistently interpreting our data.
