    • In Ref., the extrinsic term is more dominant in the clean regime than the intrinsic one, which seems to be inconsistent with Refs.and. However, the extrinsic term strongly depends on the property of impurity, in other words, its orbital degrees of freedom as detailed in Ref. In this sense, the statement about the extrinsic term in Ref. is not general.

    • Equation in the present paper is different from Eq. in Ref. by a factor of 2 in front of the hyperbolic sine term. In the present paper we take into account only one path for spin relaxation whose direction is perpendicular to the plane of the TM middle wires. On the other hand, in Ref. there are two paths for the spin relaxation, i.e., side edges of the TM wires. Since the spin-diffusion lengths of the TM wires are extremely small, spin current should be absorbed perpendicularly into the plane of the TM wires, not from the side edges. It is known that the former model gives a better fitting for the distance dependence of NLSV than the latter one (see Ref.).

    • The spin resistance defined here is expressed by ρλ/A. This means that a larger spin resistance corresponds to less spin-diffusion processes, which is intuitively opposite to a normal resistance.
