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.

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
