标题： Anisotropy-Driven Anomalous Inverse Orbital Hall Effect in Fe Films

摘要： 这项研究探讨了具有强单轴各向异性的铁（Fe）薄膜中的异常轨道效应，强调了自旋和轨道电流之间的相互作用。 使用通过磁场中倾斜沉积制备的异质结构YIG/Fe和YIG/Pt/Fe，进行了自旋泵浦铁磁共振（SP-FMR）测量。 观察到单轴各向异性使得在面外配置中出现了自旋到电荷（AISHE）和轨道到电荷（AIOHE）转换信号，其中自旋极化方向与自旋电流方向平行。 实验分析表明，由于自旋-轨道相互作用（SOC）较低和轨道响应较高，轨道动力学通过轨道霍尔电导率更为显著。 这些发现为轨道电子器件的发展提供了基本见解，表明可以通过磁性和各向异性参数控制轨道和自旋电流。 显示英文摘要

摘要： This study investigates the anomalous orbital effects in iron (Fe) films with strong uniaxial anisotropy, highlighting the interactions between spin and orbital currents. Using heterogeneous YIG/Fe and YIG/Pt/Fe structures, fabricated by oblique deposition in a magnetic field, spin pumping ferromagnetic resonance (SP-FMR) measurements were performed. It was observed that the uniaxial anisotropy enables the emergence of spin-to-charge (AISHE) and orbital-to-charge (AIOHE) conversion signals in out-of-plane configurations, where the spin polarization is parallel to the direction of the spin current. Experimental analysis revealed that orbital dynamics, mediated by orbital Hall conductivity, are more prominent in Fe films due to the low spin-orbit interaction (SOC) and high orbital response. These findings provide fundamental insights for the advancement of orbitronics devices, indicating the potential for controlling orbital and spin currents through magnetic and anisotropic parameters.
