Eddy Current Testing of Metal Cracks Using Spin Hall Magnetoresistance Sensor and Machine Learning
Yanjun Xu, Yumeng Yang, Yihong Wu
Recently we have developed a spin Hall magnetoresistance (SMR) sensor which operates under AC bias and sense currents. Here we demonstrate both theoretically and experimentally tha…
Terahertz Emission From an Exchange-Coupled Synthetic Antiferromagnet
Qi Zhang, Yumeng Yang, Ziyan Luo +4
We report on terahertz emission from FeMnPt/Ru/FeMnPt and Pt/CoFeB/Ru/CoFeB/Pt synthetic antiferromagnet (SAF) structures upon irradiation by a femtosecond laser; the former is via…
Magnetic angular position sensor enabled by spin-orbit torque
Ziyan Luo, Yanjun Xu, Yumeng Yang +1
We propose a simple scheme for magnetic angular position sensor based on current-induced spin-orbit torque effect. A full range detection of 360o is realized with a pair of Hall cr…
Anomalous Hall magnetoresistance in a ferromagnet
Yumeng Yang, Ziyan Luo, Haijun Wu +5
The anomalous Hall effect, observed in conducting ferromagnets with broken time-reversal symmetry, offers the possibility to couple spin and orbital degrees of freedom of electrons…
Selective multiple domain wall injection using spin-orbit torque
Ziyan Luo, Wugang Liao, Yumeng Yang +2
We demonstrate from both simulation and experiment a simple scheme for selective injection of multiple domain walls in a magnetic nanowire. The structure consists of a side-contact…
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…

Yumeng Yang, Yanjun Xu, Hang Xie +2
We demonstrate an ultrathin and semitransparent anisotropic and spin Hall magnetoresistance sensor based on NiFe/Pt heterostructure. The use of spin-orbit torque effective field fo…
Static and Dynamic Magnetic Properties of FeMn/Pt Multilayers
Ziyan Luo, Yumeng Yang, Yanjun Xu +4
Recently we have demonstrated the presence of spin-orbit toque in FeMn/Pt multilayers which, in combination with the anisotropy field, is able to rotate its magnetization consecuti…
Unveiling the role of Co-O-Mg bond in magnetic anisotropy of Pt/Co/MgO using atomically controlled deposition and in-situ electrical measurement
Yumeng Yang, Jiaren Yuan, Long Qi +7
Despite the crucial role of interfacial perpendicular magnetic anisotropy in Co(Fe)/MgO based magnetic tunnel junction, the underlying mechanism is still being debated. Here, we re…
Self-current induced spin-orbit torque in FeMn/Pt multilayers
Yanjun Xu, Yumeng Yang, Kui Yao +2
Extensive efforts have been devoted to the study of spin-orbit torque in ferromagnetic metal/heavy metal bilayers and exploitation of it for magnetization switching using an in-pla…
