The SOT is decomposed into two contributions, namely, {\\it spin-Hall} and the {\\it spin-orbital} components. We find that {\\it (i)} the Field-Like (FL) SOT is dominated by the spin-orbital component and {\\it (ii)} both components contribute to the damping-like torque with comparable magnitude in the limit of thick Pt film.
