AI 中文摘要
铁磁体中的自旋依赖输运是高密度自旋电子存储器发展的基础，强自旋轨道耦合铁磁体中的自旋依赖输运表现出显著各向异性。当磁化强度偏离晶体易轴，或电场相对于晶轴旋转时，电荷输运过程中的整体自旋极化与磁自旋霍尔电导率均呈现明显各向异性，这些各向异性响应主要源于自旋轨道耦合，其被确定为铁磁体中观测到的大各向异性的关键驱动因素。此外，还证实了磁自旋霍尔各向异性的应变可调性，拉伸应变会逐步增大自旋霍尔电导率的振荡幅度。这些发现确立了强自旋轨道耦合铁磁体作为各向异性自旋电流产生及无场自旋电子器件的平台，该器件可利用本征材料各向异性提升性能与能效。
英文摘要
Spin-dependent transport in ferromagnets underpins the development of high-density spintronic memories. Spin-dependent transport in strong spin-orbit-coupled ferromagnets exhibits a significant anisotropy. Both the overall spin polarization during charge transport and the magnetic spin Hall conductivity are found to exhibit pronounced anisotropy when the magnetization is tilted away from the crystallographic easy axis or when the electric field is rotated relative to the crystal axes. These anisotropic responses originate primarily from spin-orbit coupling, which is identified as the key driver of the large anisotropy observed in ferromagnet. Furthermore, strain tunability of the magnetic spin Hall anisotropy is demonstrated, with tensile strain progressively enhancing the oscillatory amplitude of the spin Hall conductivity. These findings establish strong spin-orbit-coupled ferromagnets as a platform for anisotropic spin-current generation and field-free spintronic devices that exploit intrinsic material anisotropy for improved performance and energy efficiency.
