All electrical manipulation of magnetization in an Y3Fe5O12 (YIG)/Pt system was crucial to develop magnon-based spintronic devices. In this study, we realized spin-orbit torque (SOT) switching in perpendicular YIG/Pt films. Perpendicular magnetic anisotropy of YIG was induced by strain from the bottom substrate and also influenced by the capping Pt layer and subsequent annealing. Besides, SOT efficiency of the YIG/Pt system was also measured. Damping-like torque with an efficiency of 0.98Oe/(MA/cm(2)) was the dominating term to contribute to the SOT switching. This work was beneficial to construct electrically controllable magnon devices.
