Single-shot dynamics of spin–orbit torque and spin transfer torque switching in three-terminal magnetic tunnel junctions [PDF]
Nature Nanotechnology, 2020 Current-induced spin-transfer torques (STT) and spin–orbit torques (SOT) enable the electrical switching of magnetic tunnel junctions (MTJs) in non-volatile magnetic random access memories.

Three-Dimensional Dynamics of a Magnetic Hopfion Driven by Spin Transfer Torque. [PDF]
Physical Review Letters, 2020 Magnetic hopfion is a three-dimensional (3D) topological soliton with novel spin structure that would enable exotic dynamics. Here, we study the current-driven 3D dynamics of a magnetic hopfion with a unit Hopf index in a frustrated magnet. Attributed to

Evidence for Thermal Spin-Transfer Torque [PDF]
Physical Review Letters, 2010 Large heat currents are obtained in Co/Cu/Co spin valves positioned at the middle of Cu nanowires. The second harmonic voltage response to an applied current is used to investigate the effect of the heat current on the switching of the spin valves. Both the switching field and the magnitude of the voltage response are found to be dependent on the heat ...

Spin Pumping and Spin-Transfer Torques in Antiferromagnets [PDF]
Physical Review Letters, 2014 Spin pumping and spin-transfer torques are two reciprocal phenomena widely studied in ferromagnetic materials. However, pumping from antiferromagnets and its relation to current-induced torques have not been explored. By calculating how electrons scatter off a normal metal-antiferromagnetic interface, we derive pumped spin and staggered spin currents ...

Spin transfer torque switching dynamics in CoFeB/MgO magnetic tunnel junctions
Physical review B, 2021 We perform atomistic simulations of spin transfer torque switching dynamics in CoFeB/MgO/CoFeB magnetic tunnel junctions. We base our study on Slonczewski's model parametrized following the approach of Zhang, Levy, and Fert.
