In-situ study of oxygen exposure effect on spin-orbit torque in Pt/Co bilayers in ultrahigh vacuum
Hang Xie, Jiaren Yuan, Ziyan Luo +2
Oxygen incorporation has been reported to increase the current-induced spin-orbit torque in ferromagnetic heterostructures, but the underlying mechanism is still under active debat…
Disentangle magnon magnetoresistance from anisotropic and spin Hall magnetoresistance in NiFe/Pt bilayers
Yanjun Xu, Yumeng Yang, Ziyan Luo +1
We conducted a systematic angular dependence study of nonlinear magnetoresistance in NiFe/Pt bilayers at variable temperature and field using the Wheatstone bridge method. We succe…
Intrinsic skyrmions in monolayer Janus magnets
Jiaren Yuan, Yumeng Yang, yongqing Cai +5
Skyrmions are localized solitonic spin textures with protected topology, which are promising as information carriers in ultra-dense and energy-efficient logic and memory devices. R…
Spin-Orbit Torque in a Single Ferromagnetic Layer with Large Spin-Orbit Coupling

We reported a systematic study of spin-orbit torque biased magnetic sensors based on NiFe/Pt bilayers through both macro-spin modeling and experiments. The simulation results show…
Thickness dependence of spin Hall magnetoresistance in FeMn/Pt bilayers
Yumeng Yang, Yanjun Xu, Kui Yao +1
We investigated spin Hall magnetoresistance in FeMn/Pt bilayers, which was found to be one order of magnitude larger than that of heavy metal and insulating ferromagnet or antiferr…
Field-like spin orbit torque in ultra-thin polycrystalline FeMn films
Yumeng Yang, Yanjun Xu, Xiaoshan Zhang +6
Field-like spin orbit torque in FeMn/Pt bilayers with ultra-thin polycrystalline FeMn has been characterized through planar Hall effect measurements. A large effective field is obt…
Dynamic Control of Local Field Emission Current from Carbon Nanowalls
Ying Wang, Yumeng Yang, Yihong Wu
We report on a systematic study of modulation of the field emission current from carbon nanowalls using a sharp probe as the anode in an ultrahigh vacuum system. Modulation of the…
Investigation of Magnetic Proximity Effect inTa/YIG Bilayer Hall Bar Structure
Yumeng Yang, Baolei Wu, Kui Yao +3
In this work, the investigation of magnetic proximity effect was extended to Ta which has been reported to have a negative spin Hall angle. Magnetoresistance and Hall measurements…
Local Electron Field Emission Study of Two-dimensional Carbon
Ying Wang, Yumeng Yang, Zizheng Zhao +2
A systematic field-emission study has been carried out on different types of two-dimensional carbons in ultrahigh vacuum with the cathode-anode distance ranging from near-contact t…
