Orbital torque switching of room temperature two-dimensional van der Waals ferromagnet Fe3GaTe2

Orbital torque device based on 2D-vdW ferromagnet

In 2D-vdW FM SOT heterostructures, the J_S can be generated by SHMs [e.g., Pt^34,35,36, Bi_1.1Sb_0.9Te₂S₁³⁷, and WTe₂³⁹], and then these J_S flow into 2D-vdW ferromagnets, exerting a torque that…
