论文摘要
在Spintronic实验中经常观察到铁磁和金属层之间界面的有效场。通常，将其归因于由自旋轨道耦合引起的特定交换相互作用，即Rashba场，Dzyaloshinskiy-Moriya相互作用，自旋电流等。替代视图涉及由导体内部和外部电流产生的全球磁场（OERSTED场）。这里显示的是，围绕铁磁层周围的不均匀散落场可以在观察到的界面场中产生重大贡献。应考虑这种机制，以更好地理解磁性多层中电流诱导的现象。
The effective field at the interface between ferromagnetic and metal layers is often observed in spintronic experiments. It is common to ascribe it to specific exchange interactions caused by spin-orbit coupling, namely, Rashba field, Dzyaloshinskiy-Moriya interaction, spin currents, etc. Alternative view involves the global magnetic field (Oersted field) generated by current both inside and outside the conductor. It is shown here that the inhomogeneous stray field surrounding ferromagnetic layers can produce significant contribution into the observed interface field. This mechanism should be taken into account for better understanding the current-induced phenomena in magnetic multilayers.
