Epitaxial Strain Activates Altermagnetic Spin-Splitting Torques in RuO2(100)
Qi Jia, Seung Gyo Jeong, Seungjun Lee +10
The altermagnetic nature of rutile RuO2 remains under active debate: bulk measurements indicate a nearly nonmagnetic ground state, whereas thin-film studies have reported symmetry-…
High-Frequency Switching in Superparamagnetic Magnetic Tunnel Junctions by Enhancing Damping
Qi Jia, Jian-Ping Wang
Superparamagnetic magnetic tunnel junctions (sMTJs) are promising components for true random number generation and probabilistic computing. Achieving high-frequency fluctuation whi…
Interface-engineered voltage-driven magnetic tunnel junctions with ultra-low-energy magnetization switching
Yu Zhang, Meng Xu, Bowei Zhou +9
Electric-field control of spin states offers a promising route to ultra-low-power, ultra-fast magnetization switching in spintronic devices such as magnetic tunnel junctions (MTJs)…
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.…
Anomalous vortex Hall effect in a ferromagnet/superconductor heterostructure
Weideng Sun, Przemyslaw Swatek, Yihong Fan +5
The coexistence of superconductivity and ferromagnetism is a fascinating and complex phenomenon in condensed matter physics, as these two states are typically mutually exclusive du…
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…
