在Y3 Fe 5 O 12（YIG）/Pt混合结构中观察到由表面声波（SAW）产生的自旋电流。在YIG/Pt界面处，发现在YIG层中产生的SAW将自旋电流泵入Pt层，这是通过Pt中的逆自旋霍尔效应检测到的。YIG/Pt横向结构与压电楔形换能器相结合，使系统的调查，由于在YIG中的SAW的自旋电压分布。由于所观察到的现象与基于SAW的电子学具有很高的亲和力，它将为构建自旋电子SAW器件铺平道路。
A spin current generated from a surface acoustic wave (SAW) was observed in an Y3Fe5O12 (YIG)/Pt hybrid structure. At the YIG/Pt interface, a SAW generated in the YIG layer was found to pump a spin current into the Pt layer, which was detected through the inverse spin-Hall effect in the Pt. The YIG/Pt lateral structure combined with a piezoelectric wedge transducer enables the systematic investigation of the spin-voltage distribution due to the SAW in the YIG. Since the observed phenomenon has high affinity with SAW-based electronics, it will pave the way for constructing spintronic SAW devices.
