研究了[Pt/Co]n/α-Cr_2O_3超晶格铁磁/反铁磁界面的垂直磁各向异性。通过改变堆积周期数,分别估算了Co/α-Cr_2O_3和Pt/Co界面对PMA的贡献。结果表明,在Co/α-Cr_2O_3界面和Pt/Co界面上均存在强烈的PMA诱导。界面磁各向异性能密度随铁磁层成分的变化支持了Co/α-Cr2 O3界面的PMA。据我们所知,这是PMA在铁磁/反铁磁界面的第一次演示。
We have investigated the perpendicular magnetic anisotropy (PMA) at the ferromagnetic/antiferromagnetic interface using [Pt/Co]n/α-Cr2O3 superlattices. By changing the number of stacking periods, the contributions of the Co/α-Cr2O3 and Pt/Co interfaces to the PMA are separately estimated. The results indicate that the strong PMA is induced at the Co/α-Cr2O3 interface as well as at the Pt/Co interface. The change in the interface magnetic anisotropy energy density with the ferromagnetic layer composition supports the PMA at the Co/α-Cr2O3 interface. To the best of our knowledge, this is the first demonstration of PMA at the ferromagnetic/antiferromagnetic interface.
