近年来，对 3d 过渡金属及其合金的自旋注入进行了深入研究。在这项研究中，我们重点关注 FeRh 合金，它经常用于反铁磁自旋电子学领域。我们通过自旋力矩铁磁共振探索了 FeRh 中自旋电流和磁矩之间的相互作用。我们得到的自旋霍尔效率为 ψSH = 24 ± 3%，这表明来自 Pt 的自旋电流与 FeRh 中的磁矩相互作用。
Spin injection into 3d transition metals and their alloys has been investigated intensively in recent years. In this study, we focus on the FeRh alloy, which is often used in the context of antiferromagnetic spintronics. We explore the interaction between the spin current and magnetic moments in FeRh by means of spin-torque ferromagnetic resonance. We obtain a spin Hall efficiency of ξSH = 24 ± 3%, which indicates that the spin current from Pt interacts with the magnetic moments in FeRh.
