Transverse magnetothermoelectric effects are studied in permalloy thin films grown on MgO substrates. We find that small parasitic magnetic fields below 1 Oe can produce artifacts of the order of 1% of the amplitude of the anisotropic magnetothermopower which is also detected in the experiments. The measured artifacts reveal a new source of uncertainties for the detection of the transverse spin Seebeck effect in conductive ferromagnets. Taking these results into account we conclude that the… 

Quantitative separation of the anisotropic magnetothermopower and planar Nernst effect by the rotation of an in-plane thermal gradient

The angular dependence of the magnetothermopower with respect to the magnetization direction reveals a phase shift, that allows the quantitative of the thermopower, the anisotropic magnetotheropower and the planar Nernst effect in a permalloy thin film.

Comment on “Optical detection of transverse spin-Seebeck effect in permalloy film using Sagnac interferometer microscopy”

Measuring spin currents and spin accumulations is challenging. This is mainly because of their small size and the lack of a standard spin detector comparable to conventional ampere meters or voltage
