Oscillatory spin-orbit torque switching induced by field-like torques
Jong Min Lee, Jae Hyun Kwon, Rajagopalan Ramaswamy +7
Deterministic magnetization switching using spin-orbit torque (SOT) has recently emerged as an efficient means to electrically control the magnetic state of ultrathin magnets. The…
Experimental study of extrinsic spin Hall effect in CuPt alloy
Rajagopalan Ramaswamy, Yi Wang, Mehrdad Elyasi +4
We have experimentally studied the effects on the spin Hall angle due to systematic addition of Pt into the light metal Cu. We perform spin torque ferromagnetic resonance measureme…
Anomalous current-induced spin torques in ferrimagnets near compensation
Rahul Mishra, Jiawei Yu, Xuepeng Qiu +3
While current-induced spin-orbit torques (SOTs) have been extensively studied in ferromagnets and antiferromagnets, ferrimagnets have been less studied. Here we report the presence…
Continuous Tuning the Magnitude and Direction of Spin-Orbit Torque Using Bilayer Heavy Metals
Pan He, Xuepeng Qiu, Vanessa L. Zhang +3
Spin-orbit torques (SOTs) have opened a new path to switch the magnetization in perpendicularly magnetized films and are of great interest due to their potential applications in no…
Tunable terahertz reflection of graphene via ionic liquid gating
Yang Wu, Xuepeng Qiu, Hongwei Liu +4
We report a highly efficient tunable THz reflector in graphene. By applying a small gate voltage (up to 3 V), the reflectance of graphene is modulated from a minimum of 0.79% to a…
