The paper we comment on reports measurements of the transverse spin-Seebeck effect in metals using a novel technique. We provide an estimation of the size of the effect reported by McLaughlin et al. [Phys. Rev. B 95, 180401 (2017)], which turns out to be exceptionally large: comparison of the estimated amount of spin accumulation with the spin-dependent Seebeck effect would require a temperature difference of the order of 1000 K. Considering the null results reported in previous papers, we suggest that the signal measured by McLaughlin et al. is not or not only caused by the transverse spin-Seebeck effect.
