Observation of Thickness-Modulated Out-of-Plane Spin-Orbit Torque in Polycrystalline Few-Layer Td-WTe2 Film
{{output}}
The low-symmetry Weyl semimetallic Td-phase WTe2 exhibits both a distinct out-of-plane damping torque (τDL) and exceptional charge-spin interconversion efficiency enabled by strong spin-orbit coupling, positioning it as a prime candidate for spin-orbit torque... ...
