Laser-intensity-spike-dominated hot electron generation from two-plasmon decay instability driven by moderate-bandwidth pulses
C. Yao, Z. H. Cai, X. Wang +34
Our direct-drive-relevant experiments on the low-coherence Kunwu laser facility identify two-plasmon decay (TPD) as the primary source of hot electrons, and demonstrate for the fir…
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…
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.…
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…
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…
