新型界面驱动自旋电子效应的预测

Prediction of novel interface-driven spintronic effects

Satadeep Bhattacharjee, Surendra Singh, Dawei Wang, Michel Viret, Laurent Bellaiche

摘要:

最近提出的角动量密度和磁矩之间的耦合[A. Raeliarijaona等人,Phys.Rev.Lett. 110,137205(2013)]在此示出以导致预测(i)由电流产生的新自旋电流和(ii)由自旋电流在具有两种不同材料之间的特定界面的系统中感应的新电流。其中一些自旋(电)电流可以通过反转所施加的电流(自旋)来在界面附近反转。这些新的自旋电子效应和著名的自旋霍尔和反自旋霍尔效应之间的异同进行了讨论。

英文摘要:

The recently-proposed coupling between the angular momentum density and magnetic moment [A. Raeliarijaona et al, Phys. Rev. Lett. 110, 137205 (2013)] is shown here to result in the prediction of (i) novel spin currents generated by an electrical current and (ii) new electrical currents induced by a spin current in systems possessing specific interfaces between two different materials. Some of these spin (electrical) currents can be reversed near the interface by reversing the applied electrical (spin) current. Similarities and differences between these novel spintronic effects and the well-known spin Hall and inverse spin Hall effects are also discussed.
