Energy-efficient spin Hall nano-oscillators using near-compensated CoGd ferrimagnets
Jiayu Lei, Raghav Sharma, Shishun Zhao +5
Conventional spin Hall nano-oscillators (SHNOs) based on ferromagnets face practical limitations due to high threshold current densities and large external magnetic field requireme…
Mimicking synaptic plasticity with wedged Pt/Co/Pt spin-orbit torque device
Shiwei Chen, Mishra Rahul, Huanjian Chen +2
We fabricated a wedge-shaped Pt/Co/Pt device with perpendicular magnetic anisotropy and manifested that the Co magnetization can be solely switched by spin-orbit torque without any…

Room temperature magnetization switching in topological insulator-ferromagnet heterostructures by spin-orbit torques
Yi Wang, Dapeng Zhu, Yang Wu +9
Topological insulators (TIs) with spin momentum locked topological surface states (TSS) are expected to exhibit a giant spin-orbit torque (SOT) in the TI/ferromagnet systems. To da…
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…
Coherent Sub-Nanosecond Switching of Perpendicular Magnetization by the Field-like Spin-Orbit Torque without an External Magnetic Field
William Legrand, Rajagopalan Ramaswamy, Rahul Mishra +1
We theoretically study the influence of a predominant field-like spin-orbit torque on the magnetization switching of small devices with a uniform magnetization. We show that for a…
