Demonstration of Electron-Mediated Voltage-Controlled Exchange Coupling in Perpendicular Magnetic Tunnel Junctions
Qi Jia, Yu-Chia Chen, Delin Zhang +8
Electron-mediated voltage control of exchange coupling (EM-VCEC) has been proposed as a mechanism for magnetization switching via modulation of spin-dependent electron reflection.…
Energy Efficient Stochastic Signal Manipulation in Superparamagnetic Tunnel Junctions via Voltage-Controlled Exchange Coupling
Qi Jia, Onri J. Benally, Brandon Zink +8
Superparamagnetic tunnel junctions (sMTJs) are emerging as promising components for stochastic units in neuromorphic computing, owing to their tunable random switching behavior. Co…
Coexistence of unconventional spin Hall effect and antisymmetric planar Hall effect in IrO
Yifei Yang, Sreejith Nair, Yihong Fan +9
Crystal symmetry plays an important role in the Hall effects. Unconventional spin Hall effect (USHE), characterized by Dresselhaus and out-of-plane spins, has been observed in mate…
Robust negative longitudinal magnetoresistance and spin-orbit torque in sputtered Pt3Sn topological semimetal
Delin Zhang, Wei Jiang, Hwanhui Yun +11
Contrary to topological insulators, topological semimetals possess a nontrivial chiral anomaly that leads to negative magnetoresistance and are hosts to both conductive bulk states…
Perpendicular magnetic anisotropy, tunneling magnetoresistance and spin-transfer torque effect in magnetic tunnel junctions with Nb layers
Bowei Zhou, Pravin Khanal, Onri Jay Benally +7
Nb and its compounds are widely used in quantum computing due to their high superconducting transition temperatures and high critical fields. Devices that combine superconducting p…
Room temperature spin-orbit torque efficiency in sputtered low-temperature superconductor delta-TaN
Przemyslaw Wojciech Swatek, Xudong Hang, Yihong Fan +14
In the course of searching for promising topological materials for applications in future topological electronics, we evaluated spin-orbit torques (SOTs) in high-quality sputtered…
Element Doping Enhanced Charge-to-Spin Conversion Efficiency in Amorphous PtSn4 Dirac Semimetal
Jinming Liu, Yihong Fan, Delin Zhang +4
Topological semimetals (TSs) are promising candidates for low-power spin-orbit torque (SOT) devices due to their large charge-to-spin conversion efficiency. Here, we investigated t…
Thermal Contribution in the Electrical Switching Experiments with Heavy Metal / Antiferromagnet Structures
Peng Sheng, Zhengyang Zhao, Onri Jay Benally +2
We examine the thermal origin of the detected "saw-tooth" shaped Hall resistance (Rxy) signals in the spin-orbit torque switching experiment for antiferromagnetic MnN. Compared wit…
