Magnetization switching in polycrystalline Mn3Sn thin film induced by self-generated spin-polarized current
Hang Xie, Xin Chen, Qi Zhang +4
Electrical manipulation of spins is essential to design state-of-the-art spintronic devices and commonly relies on the spin current injected from a second heavy-metal material. The…
Giant enhancement of anomalous Hall effect in Cr modulation-doped non-collinear antiferromagnetic Mn3Sn thin films
Xin Chen, Hang Xie, Qi Zhang +3
We report on Cr doping effect in Mn3Sn polycrystalline films with both uniform and modulation doping. It is found that Cr doping with low concentration does not cause notable chang…
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…
