利用反常霍尔效应（AHE）研究了两层铁磁层之间的层间交换耦合（IEC）和界面磁各向异性（Ki）.样品由具有垂直磁各向异性的Co0.75Fe2.25O4层和具有面内各向异性的Fe层组成，由具有可变厚度的MgO层隔开。由于Co0.75Fe2.25O4和MgO是绝缘体，因此AHE信号仅反映Fe的磁化过程。由此，我们确定了IEC和Ki。证实了Co_（0.75）Fe_（2.25）O_4与Fe之间存在强反铁磁IEC。在直接耦合的Fe和Co0.75Fe2.25O4中观察到最强的IEC为− 1.1 mJ/m2，Ki为−1.1 mJ/m2。
We investigated interlayer exchange coupling (IEC) and interface magnetic anisotropy (Ki) between two ferromagnetic layers with crossed in-plane and perpendicular magnetic anisotropies separated by a non-magnetic spacer by using the anomalous Hall effect (AHE). The sample consisted of a Co0.75Fe2.25O4 layer with perpendicular magnetic anisotropy and a Fe layer with in-plane anisotropy, separated by a MgO layer with variable thickness. Since Co0.75Fe2.25O4 and MgO are insulators, the AHE signal only reflects the magnetization process of Fe. From this, we determined both IEC and Ki. A strong antiferromagnetic IEC was confirmed between Co0.75Fe2.25O4 and Fe. The strongest IEC of −1.1 mJ/m2 was observed for directly coupled Fe and Co0.75Fe2.25O4 for which Ki was −1.1 mJ/m2.
