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-…

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…
