| 英文摘要 | Using a heavy-metal (HM) alloy layer in spin-orbit torque (SOT)based devices is an effective method for obtaining a high current-spin conversion efficiency OSH. In this work, SOT-based spintronic devices with a Pt100-xRux-alloyed HM layer are studied by applying harmonic Hall measurements and magneto-optical Kerr effect microscopy to detect the OSH and to observe the process of current-induced magnetization switching. Both the highest OSH of 0.132 and the lowest critical current density (Jc) of 8 x 105 A/cm2 are realized in a device with x = 20, which satisfies the high SOT efficiency and low energy consumption simultaneously. The interfacial Dzyaloshinskii-Moriya interaction can be overcome by increasing the in-plane assist field. Meanwhile, the minimum in-plane field required for current-induced complete switching can be reduced to +/- 60 Oe. Our study reveals that using the Pt-Ru alloyed HM layer is an effective route for SOT application with enhanced performance. |
