Dzyaloshinskii-Moriya相互作用已被证明可以稳定磁性薄膜中的Nèel磁畴壁,从而在自旋电流效应的驱动下实现高磁化磁化壁速度。界面Dzyaloshinskii-Moriya相互作用(IDMI)发生在具有强自旋轨道耦合的铁磁性和重金属层之间的界面上,但相互作用的细节尚不清楚,邻近感应磁性(PIM)在重金属中的作用也尚不清楚。在这里,IDMI和PIM在铂中被报告,被确定为铂/钴/金,Ir/铂中Au和Ir间隔层的函数。这两种相互作用都被发现对间隔物厚度的亚纳米级变化很敏感,在亚单层间隔物厚度上相互关联,但对于较厚的间隔物,即使在失去PIM之后,IDMI仍继续变化。
The Dzyaloshinskii-Moriya interaction has been shown to stabilise Nèel domain walls in magnetic thin films, allowing high domain wall velocities driven by spin current effects. The interfacial Dzyaloshinskii-Moriya interaction (IDMI) occurs at the interface between ferromagnetic and heavy metal layers with strong spin-orbit coupling, but details of the interaction remain to be understood and the role of proximity induced magnetism (PIM) in the heavy metal is unknown. Here IDMI and PIM are reported in Pt determined as a function of Au and Ir spacer layers in Pt/Co/Au,Ir/Pt. Both interactions are found to be sensitive to sub-nanometre changes in the spacer thickness, correlating over sub-monolayer spacer thicknesses, but not for thicker spacers where IDMI continues to change even after PIM is lost.
