Measurement of spin–orbit torque using field counterbalancing in radial current geometry [PDF]

Scientific Reports, 2023
Controlling the direction of magnetization with an electric current, rather than a magnetic field, is a powerful technique in spintronics. Spin–orbit torque, which generates an effective magnetic field from the injected current, is a promising method for

Giant Spin‐Orbit Torque in Sputter‐Deposited Bi Films [PDF]

Advanced Science, 2023
Bismuth (Bi) has the strongest spin‐orbit coupling among non‐radioactive elements and is thus a promising material for efficient charge‐to‐spin conversion.

Terahertz oscillation driven by optical spin-orbit torque [PDF]

Nature Communications
Antiferromagnets are promising for nano-scale oscillator in a wide frequency range from gigahertz up to terahertz. Experimentally realizing antiferromagnetic moment oscillation via spin-orbit torque, however, remains elusive.

Tunable unconventional spin orbit torque magnetization dynamics in van der Waals heterostructures [PDF]

Nature Communications
Two-dimensional quantum material heterostructures can offer a promising platform for energy-efficient non-volatile spin-based technologies. However, spin dynamics experiments to understand the basic spin-orbit torque phenomena are so far lacking.

Terahertz spin dynamics driven by an optical spin-orbit torque

Physical Review Research, 2021
Spin torques are at the heart of spin manipulations in spintronic devices. Here, we examine the existence of an optical spin-orbit torque, a relativistic spin torque originating from the spin-orbit coupling of an oscillating applied field with the spins.
