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…
Semitransparent anisotropic and spin Hall magnetoresistance sensor enabled by spin-orbit toque biasing
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…
