Roadmap of spin-orbit torques
Qiming Shao, Peng Li, Luqiao Liu +16
Spin-orbit torque (SOT) is an emerging technology that enables the efficient manipulation of spintronic devices. The initial processes of interest in SOTs involved electric fields,…
A Thermodynamic Core using Voltage-Controlled Spin-Orbit-Torque Magnetic Tunnel Junctions
Albert Lee, Bingqian Dai, Di Wu +3
We present a magnetic implementation of a thermodynamic computing fabric. Magnetic devices within computing cores harness thermodynamics through its voltage-controlled thermal stab…
Dipole-phonon quantum logic with alkaline-earth monoxide and monosulfide cations
Michael Mills, Hao Wu, Evan C. Reed +6
Dipole-phonon quantum logic (DPQL) leverages the interaction between polar molecular ions and the motional modes of a trapped-ion Coulomb crystal to provide a potentially scalable…
Chiral symmetry breaking for deterministic switching of perpendicular magnetization by spin-orbit torque
Hao Wu, John Nance, Seyed Armin Razavi +11
Symmetry breaking is a characteristic to determine which branch of a bifurcation system follows upon crossing a critical point. Specifically, in spin-orbit torque (SOT) devices, a…
Picosecond spin-orbit torque switching of ferrimagnets
Hao Wu, Deniz Turan, Quanjun Pan +6
Spintronics provides an efficient platform for realizing non-volatile memory and logic devices. In these systems, data is stored in the magnetization of magnetic materials, and mag…
Experimental creation and annihilation of nonvolatile magnetic skyrmions using voltage control of magnetic anisotropy without an external magnetic field
Dhritiman Bhattacharya, Seyed Armin Razavi, Hao Wu +3
In this work, we utilize voltage controlled magnetic anisotropy (VCMA) to manipulate magnetic skyrmions that are fixed in space. Memory devices based on this strategy can potential…
