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…
Correlation between Dzyaloshinskii Moriya interaction and spin mixing conductance at antiferromagnet / ferromagnet interface
Xin Ma, Guoqiang Yu, Seyed A. Razavi +6
The rich interaction phenomena at antiferromagnet (AFM)/ ferromagnet (FM) interfaces are key ingredients in AFM spintronics, where many underlying mechanisms remain unclear. Here w…
Role of dimensional crossover on spin-orbit torque efficiency in magnetic insulator thin films
Qiming Shao, Chi Tang, Guoqiang Yu +19
Magnetic insulators (MIs) attract tremendous interest for spintronic applications due to low Gilbert damping and absence of Ohmic loss. Magnetic order of MIs can be manipulated and…
Dzyaloshinskii Moriya interaction across antiferromagnet / ferromagnet interface
Xin Ma, Guoqiang Yu, Seyed A. Razavi +6
The antiferromagnet (AFM) / ferromagnet (FM) interfaces are of central importance in recently developed pure electric or ultrafast control of FM spins, where the underlying mechani…
