Fig. 5
Anisotropic spin conductivity in WTe2/Py devices. The spin conductivity σFL calculated using the extracted FL torque in WTe2/Py with the current along the a- and b-axes. The thicknesses of the WTe2 in the Hall devices are 5.6 nm (a), 7.0 nm (b), 20.0 nm (c), and 31.0 nm (d), respectively. The thickness of the Py in the devices is 6 nm. The dashed blue line represents the spin conductivity calculated using the estimated Oersted field. The error bar represents the combination of the 20% standard error and the fitting process
