论文摘要
已经在具有铁磁/自旋霍尔材料双层结构的多种堆栈中观察到了单向磁阻（UMR）。在这项工作中，我们报道了抗铁磁绝缘子FE2O3/PT结构中的UMR。 UMR具有负值，这与界面的Rashba耦合和束带分裂有关。依赖厚度的测量结果揭示了UMR和单向旋转霍尔磁场（USMR）之间的潜在竞争。这项工作揭示了抗铁磁绝缘体/重金属双层中的UMR存在，并为基于抗Firomagnet的Spintronic设备的应用拓宽了道路。
Unidirectional magnetoresistance (UMR) has been observed in a variety of stacks with ferromagnetic/spin Hall material bilayer structures. In this work, we reported UMR in antiferromagnetic insulator Fe2O3/Pt structure. The UMR has a negative value, which is related to interfacial Rashba coupling and band splitting. Thickness-dependent measurement reveals a potential competition between UMR and the unidirectional spin Hall magnetoresistance (USMR). This work revealed the existence of UMR in antiferromagnetic insulators/heavy metal bilayers and broadens the way for the application of antiferromagnet-based spintronic devices.
