论文摘要
经过十年的深入理论和实验探索,金属磁界面处的界面自旋轨道耦合(ISOC)是否可以有效地产生自旋电流。在这里,利用Ti/fecob双层对于可忽略不计的大型旋转大厅效应和强大的ISOC独特的ti/fecob双层,我们确定在磁性接口处通过旋转轨道滤波效果或Rashba-Edelstein(-like)(-like)即使在典型的pt/ferermagnet conterf conterf/firermag的效果上都没有明显的费用到旋转转换。各向异性。我们还发现3D Ti中的最小轨道厅效应。
After one decade of the intensive theoretical and experimental explorations, whether interfacial spin-orbit coupling (ISOC) at metallic magnetic interfaces can effectively generate a spin current has remained in dispute. Here, utilizing the Ti/FeCoB bilayers that are unique for the negligible bulk spin Hall effect and the strong tunable ISOC, we establish that there is no significant charge-to-spin conversion at magnetic interfaces via spin-orbit filtering effect or Rashba-Edelstein(-like) effect even when the ISOC is stronger than that of a typical Pt/ferromagnet interface and can promote strong perpendicular magnetic anisotropy. We also find a minimal orbital Hall effect in 3d Ti.
